Reading, summarizing, and citing literature is an essential part of every student and researcher’s life. While there are many books and workshops on academic writing, there is less information on how to efficiently organize literature. For this reason, I offer an overview of how to organize literature and notes in Zotero. Specifically, I illustrate some of my own workflows for organizing the literature for my dissertation. I also discuss general features of Zotero. The interested reader who wants to learn more will benefit from the related links.
Cross-Linguistic Colexifications with Body Concepts: Metaphor, Metonymy, Analogy
Colexification describes the relation between two meanings that are expressed with the same form in a given language. A colexification is established based on a linguistic analysis of word meanings in the same language. While the term is a cover term for different semantic relations (i.e., vagueness, polysemy, homophony), the discussion of particular types of colexifications often is connected to linguistic terminologies such as metaphor or metonymy. This is not only the case because there are prominent linguistic theories that argue for the pervasiveness of metaphor (and metonymy) in everyday life, but also because semantic relations are assumed to mirror conceptual relations. The linguistic analysis of metaphor and metonymy thus provides insights into the human mind. However, one needs to be careful to make claims about cognitive mechanisms solely based on linguistic evidence. Therefore, it is important to also consider frameworks from psychology such as analogical reasoning in order to explain the processes behind a linguistic phenomenon. In the following, I discuss ideas on metaphor and metonymy from linguistics that highlight the cognitive underpinnings of both notions, as well as a proposal for how analogical reasoning can explain their processing.
In German, we use two separate words for the body parts foot and leg: Fuß and Bein, respectively. Other languages do not make a lexical distinction between foot and leg and use the same term for both concepts, for example, noha ‘foot, leg’ in Czech (Tjuka 2019). From the perspective of the linguistic form, the term colexification can be used to describe the semantic relation between the two concepts FOOT and LEG. Colexification is a cover term for different semantic relations (François 2008). The use of an identical form to express two concepts does not necessarily indicate whether the colexification occurred due to the two concepts being related (polysemy) or unrelated (homophony). In linguistic terminology, polysemy can even be further divided into metaphor and metonymy (see Figure 1). A word like noha can be described as polysemous since the two meanings of the word are related, whereas the word bank ‘financial institution, river bank’ is homonymous because the two meanings are unrelated. Polysemy is an extension of meanings that exploit different kinds of relations: metaphorical extensions such as foot the bill based on a shared similarity between the two meanings or metonymical extensions due to a continuous relation between the meanings as in head of the department (for an overview of the terminology related to polysemy, see Vicente 2018).
Polysemy, metaphor, and metonymy are semantic relations that are assumed to have a mental reality in the human mind. Therefore, it is important to bridge the theoretical discussions about these constructs with experimental data on language processing. Here, I take a first step in that direction by describing a subset of linguistic theories about metaphor and metonymy and linking this information to a theory of analogy from psychology. In addition, I use examples of colexifications with body part terms to illustrate the scope of the terminology.
Fig. 1: Hierarchical representation of linguistic terminology and cognitive mechanisms.
Before we look more closely at metaphor, metonymy, and analogy, we need to consider the notion of domains (or frames, see Blank 1999; Koch 2001). In his discussion of the function of domains in the construction of metaphors and metonymies, Croft (1993) argued that metaphor is constructed based on a domain mapping between two distinct domains of separate matrices, whereas metonymy is the result of a domain highlighting within a domain matrix. A matrix in Croft’s proposal is comprised of matter, shape, and location (Croft 1993). This approach assumes that there is not a single semantic domain but a collection of different domains in which a given concept is integrated. The wide-ranging discussion about the term domain will not be further elaborated here because it is either used interchangeably in the linguistic literature or identifies the same theoretical framework (for a detailed discussion on the terms frame and domain, see Croft & Cruse 2004).
However, it is essential to note that domains are a defining factor in some accounts of metaphor and metonymy. Metonymy is often defined as an intradomain transfer (e.g., Wilkins 1996), whereas metaphors as an interdomain transfer (e.g., Goossens 1990; Kövecses & Radden 1998). In contrast, Riemer (2002) argued that the distinction between metonymy and metaphor cannot be based on domains alone, since the definition of the domain would influence the selection of one or the other. Nevertheless, I use the term domain in the description of examples since it is an explanatory device for particular semantic relations.
Another point that we need to keep in mind is that the distinction between metaphor and metonymy is not always clear-cut. For this reason, linguists have tried to establish new terminology to account for examples that blur the picture of distinct categories given in Figure 1. I briefly illustrate two examples. First, Goossens (1990) established the term metaphtonymy to account for the combinatory processes between metaphor and metonymy. Based on conventionalized expressions found in Longman’s Dictionary of Contemporary English, he showed that the process of deriving a metaphor from metonymy was the most frequent in the domain of sound. Metonymy within metaphor appeared in the domain of body parts only, whereas metaphor within metonymy was rare across domains. The study demonstrated intricate connections that can only be established by an in-depth semantic analysis. Second, Riemer (2002) proposed the terms hypermetonymy and hypermetaphor. He argued against Goossens’ proposal that metaphor and metonymy cannot be clearly distinguished. In Riemer’s view, some conventionalized terms grow beyond the state of pure metaphor or metonymy and evolve through the process of reinterpretation into something called hypermetonymy and hypermetaphor. I do not aim to give a final answer to this discussion but there are certainly examples from body part terms used for objects where the distinction between metaphor and metonymy is not apparent. For example, the colexification BACK-BARK could be metaphorically interpreted because the two concepts are similar in shape or as a metonymic extension based on the fact that people often lean or sit on trees with their backs.
Aristotle defined metaphor as a transfer of a name from one thing to another based on analogy (see Poetics 21 1457b). Since its establishment in classical rhetoric, metaphor has been featured in numerous important works on figurative language in philosophy and linguistics. Generally, metaphor is seen as a semantic extension across domains based on a similarity mechanism. Summarizing the vast literature on metaphor is a task for an entire dissertation. Here, I focus on giving an overview of the conceptual metaphor theory (Lakoff & Johnson 1980) and then turn to examples of meaning extension from the domain of the body to the domain of objects.
Conceptual metaphor theory is one of the most widespread and actively researched approaches to metaphors in linguistics. By demonstrating that metaphor is pervasive in everyday language, Lakoff and Johnson (1980) established a theoretical framework in which a conceptual domain is understood in terms of another. One of the most famous examples of a conceptual metaphor is ARGUMENT IS WAR which underlies expressions such as She shot down my argument. In Lakoff and Johnson’s analysis, the concrete domain of WAR is the source domain from which metaphorical expressions of the abstract domain of ARGUMENT are derived. The mappings between the conceptual domains stem from image schemas that seem to be grounded in our human experience and unidirectional. Lakoff and Johnson’s work has branched out into many directions, inspiring researchers in cognitive science (e.g., Pinker 2007) and psychology (e.g., Gibbs 1994).
Besides its huge influence on the field, the approach based on conceptual metaphor theory has also earned criticism. By postulating a conceptual metaphor based on a handful of examples in a particular language, the researchers make a generalization drawn from an unbalanced sample of data. This top-down approach is theory-driven but cannot explain all the patterns we see across languages. The theory falls short of describing the diversity of language use (for an overview of the criticism and an attempt to reconcile it with the theory, see Kövecses 2008). Another point of criticism is the assumption that the mappings are unidirectional and grounded in the sensory perception of our body. Examples of an object referring to a body part such as belly button or the semantic shift from ‘bag, purse’ to MEngl. bely (Koch 2016) show that there are counter-evidence for the embodied hypothesis.
Although Lakoff and Johnson (1980) explicitly excluded expressions such as foot of the mountain or table leg from their considerations, these expressions are shown to be an important puzzle piece in analyzing the cognitive mechanisms underlying meaning extensions. In her study on Basque, Ibarretxe-Antuñano (2012) demonstrated that body part terms are used based on spatial alignment in expressions such as mendiburu lit. ‘mountain head’, i.e., ‘mountain summit’. Furthermore, a detailed analysis of the meaning extensions of body part terms in Tzetal by Levinson (1994) showed that speakers of the language employ a geometrical algorithm to assign a body part term to a given object on the basis of shape features. Levinson (1994) argued against the assumption that this system is due to a metaphorical transfer and proposed that speakers perform a volumetric analysis of shape in line with visual object recognition. Body parts are also used to refer to landscape features in Tzeltal and in other languages (Burenhult & Levinson 2008). Here, too, shape is the decisive factor: “Whether this is metaphor or a looser form of analogy is a moot point: the body part system used with inanimate objects [i.e., landscape features] is based on geometry and shape” (Brown 2008). Especially in the case of meaning extensions across two concrete domains, it is difficult to group all occurrences under one theoretical term. Another approach to avoid the definitional maze is to use tests to account for a semantic relation between two concepts, as Urban (2012) did with an “is like” and “has something to do with” test.
In my own work, I have focused on the use of body part terms for objects, i.e., food, landscapes, plants, artifacts, etc. While I used the term body part metaphors in my MA thesis (Tjuka 2019), I have adopted the notion of colexification in my current work. There are two reasons for this decision. First, given a cross-linguistic dataset, the distinction between vagueness, polysemy, and homophony is not always straightforward. Second, the methodological advantage of using large-scale lexical datasets such as Lexibank (List et al. 2022) and the automatic creation of data collections such as CLICS (Rzymski et al. 2020) allows a bird’s eyes view of the possible connections drawn between body and object concepts found in the world’s languages. However, given the bottom-up approach, assigning the colexifications to linguistic terminology is a challenge. The colexification TOOTH-LEAF can be interpreted as based on a similarity in shape whereas HEAD-TOP can be seen as a spatial relation. Although both could be interpreted as metaphors the frequent occurrence of colexifications between HEAD and TIP OF OBJECT, CAPE (HEADLAND), or SUMMIT, as well as between TOOTH and SPROUTSHOOT, or BEAD indicate a more systematic approach to using body part terms to objects and not an on the spot creative process. Also, a directionality, as proposed by Lakoff and Johnson (1980) and advocates of grounded cognition, is distorted by the use of different body concepts for the same object. For example, HEAD or NOSE are colexified with TIP OF OBJECT. Only a few cases such as BONE-ROPE and EYE-FIRE cannot be explained by a literal similarity and thus, fall into the realm of metaphor.
Metonymy is commonly understood as a figure of speech in which a name or a part of something stands for something else. In contrast to metaphor, the meaning extension is a continuous link within the same semantic domain. Examples include mappings from part to whole as in to lend a helping hand or I saw some new faces in the crowd where a body part stands for the whole person. Due to the popularity of metaphor in linguistic theory, metonymy was long overlooked. This changed with edited volumes showing the importance of metonymy for cognitive linguistics (Kövecses & Radden 1998; Panther & Radden 1999; Barcelona 2003) and research programs developed in historical linguistics (Koch 2001, 2011; Koch & Marzo 2007). In the following, I focus on two approaches that explore meaning extensions with the help of cross-linguistic data.
In the diachronic cognitive onomasiological approach (Blank 1999, 2011; Koch 2008, 2011, 2016), a three-dimensional grid is used to illustrate the conceptual and formal relations of the source and target domains. By examining French vocabulary, Koch and Marzo (2007) developed such a grid (see Fig. 2) for the description of lexical motivation and found that the most frequent motivation in high-frequent French vocabulary is based on metonymic relations. Furthermore, Koch (2011) demonstrated the pervasiveness of metonymy as a conceptual relation of continuity in semantic changes. He defined metonymy as a figure-ground effect that highlights certain aspects within a conceptual frame and showed that it is a formal device for lexical innovation including semantic change, conversion, suffixation, prefixation, and composition.

In a cross-linguistic corpus study, Hilpert (2006) found distinctive patterns of meaning extensions of body part terms illustrating the usefulness of identifying conceptual metaphors based on a corpus analysis instead of intuitions. Similarly, Hilpert (2007) explored the assumption that meaning is established by conceptual shift, i.e., chained metonymies. In this study, he used expressions with body part terms in a corpus of 76 languages to illustrate serial extensions such as the path from OBJECTS ARE HUMAN BEINGS > PART FOR ORIENTATION > PLACE FOR ACTION expressed in back → back part → behind. This chain involves a metaphor followed by a metonymic extension and another metonymy. However, the result showed that serial extensions were not as frequent as expected and that metonymies based on metaphors were rare which supported previous findings based on English (Goossens 1990; Taylor 2002).
A domain in which metonymic extensions are frequent is the human body. Pattillo (2018) found that South American languages extend body part terms to other body part terms based on metonymy. Interestingly, the metonymy PART FOR WHOLE expressed in a HAND-ARM colexification was not as frequent as in other geographical areas such as Africa and Eurasia. Five out of 26 languages expressed the colexification as polysemy ‘hand, arm’, and another five languages as complex terms such as ‘hand-bone’. The study also showed that the metonymy PART FOR REGION represented by polysemies such as ‘hand, forearm’ and ‘hand, wrist’ was not as common as proposed by Wilkins (1996). Another metonymical pattern described in Wilkins (1996), relates to meaning extensions of body part terms to pieces of clothing or jewelry that are worn on a particular body part. Wilkins (1996) listed semantic changes such as ‘footling’ to ‘foot’ and ‘earing’ to ‘ear’ for Dravidian languages. In my study on cross-linguistic body-object colexifications, I found similar instances, for example, the colexifications WAIST-BELT, THROAT-NECKLACE, and NECK-COLLAR which can be interpreted as originating from metonymy.
The above studies from linguistics offer valuable insights into the multifaced semantic relations that occur in language. It is not surprising that a common thread throughout these studies is the expectation that there is a cognitive mechanism underlying the semantic relations of metaphor and metonymy. However, metaphor and metonymy are linguistic terms and they might not have a cognitive reality. To find out the underlying cognitive processes, linguistic evidence is not enough although it may give important hints. Therefore, I discuss a theoretical framework from psychology – analogical reasoning – that can explain some of the mechanisms expressed in the relations by which meaning extensions of body part terms are established. Metaphor has received a lot of attention from psychology and cognitive science in the past two decades (e.g., Reijnierse et al. 2019; Thibodeau & Boroditsky 2011; Speed et al. 2019, to name a few). Here, I focus on the framework by Dedre Gentner to illustrate one compelling example of how psychology can inform linguistic analysis and vice versa.
Gentner (1983) proposed a theory of analogy to describe how meaning is derived. “The central idea is that an analogy is an assertion that a relational structure that normally applies in one domain can be applied in another domain” (Gentner 1983). The basis for an analogy in her framework is a relational comparison rather than a similarity in object characteristics. The relations represent higher-order relations of the mapping which is formulated in the systematicity principle. In her view, “metaphors are predominantly relational comparisons, and are thus essentially analogies” (Gentner 1983). Building on this assumption, Gentner and her colleagues conducted several experiments to examine how metaphors are psychologically processed, summarized in an article poignantly titled Metaphor is like analogy (Gentner et al. 2001). There are two important results of these studies. First, there is a difference in how novel versus conventional metaphors are processed. The former is based on domain mapping, whereas the latter are processed as alternate word senses and thus are retrieved from stored meanings instead of an online interpretation. Second, a directionality effect in the processing of metaphors was present in that an early symmetrical alignment process was followed by directional processing. These findings are important for linguistic analysis because they reveal underlying cognitive mechanisms and provide a framework for a more informed interpretation of semantic relations.
When the use of body part terms for another body part or an object is found in dictionaries or word lists and appears as cross-linguistic colexifications, we can assume that these instances are conventional expressions. If one follows the proposal by Gentner, the distinction between metaphor and metonymy as either intra- or inter-domain mappings becomes obsolete because conventional metaphors are already stored in the mental lexicon and represent polysemous words. Thus, from a cognitive perspective, colexifications such as HAND-ARM, ARM-BRANCH, or FOOT-WHEEL should be processed similarly. Nevertheless, there are colexifications between body and object concepts that seem to be based either on continuity (NECK-COLLAR) or similarity in shape (NOSE-ARROW), space (HEAD-ROOF), or function (BLOOD VESSEL-ROOT). In my view, these conventionalized relations tell us a lot about the mechanisms that are established to form novel connections between meanings. It seems to be the case that some body-object colexifications occurred based on a perception of relations rather than object characteristics indicating that the underlying process was analogical reasoning. To work out the exact cognitive processes, future research needs to test predictions of the theoretical framework with cross-linguistic data and supplement these with experimental studies.
This overview does not claim to give a complete overview of the debate surrounding metaphor, metonymy, and analogy in relation to the use of body part terms. I have focused on a subset of the debate that highlights some of the assumptions regarding their cognitive underpinnings as well as an account of how analogical reasoning could be the underlying processing mechanism when body part terms are used for objects. Making sense of the semantic relations expressed with body part terms is a challenge, but the discussed literature provides indications on how to interpret the cross-linguistic patterns and the linguistic diversity that we see. The generalizations given in terms of cognitive mechanisms can also inform linguistic analysis, allowing for an overarching picture without getting lost in the peculiarities of individual languages.

The Origins of Cross-Linguistic Colexifications
In recent years, studies exploring the phenomenon of colexification across languages have steadily increased in number. Colexification occurs if a word has multiple meanings, regardless of whether the meanings are related (dish ‘plate; meal’) or unrelated (bank ‘financial institution; part of a river’). The investigation of cross-linguistic colexifications yields many interesting findings that are important for different research fields. Psychologists and cognitive scientists are interested in the overarching principles that establish a connection between meanings and how speakers categorize the environment around them. Historical linguists are concerned with diachronic processes that lead to semantic shifts and what these can tell us about language evolution. Typologists engage in the study of language contact scenarios and how linguistic areas are formed. All these processes are entwined with one another and disentangling them is a challenge. This blog post is the first step into a deeper exploration of the origins of cross-linguistic colexifications and discusses the four processes underlying this phenomenon.
The Small Bang
The Small Bang represents a recently begun ERC-funded project dedicated to discovering the origins of the Bangime language and Bangande people. The language and its speakers are of particular interest to West African research as Bangime is one of the only isolates spoken in the region and the ancestors of the Bangande are also unknown. Using the latest computer-assisted technologies, the Bang team is amassing linguistic and genetic data and comparing them with a hitherto unexplored set of languages and peoples in search of a hidden history. Preliminary hypotheses suggest geographic isolation that has led to a bottleneck of at least 9,000 years. The question as to from whom the people and their language originated remains open.
Creating Custom Commands in CLDF: From Lexibank to Nexus Files
Thanks to the CLDFBench Python package, CLDF datasets compiled with CLDFbench have a rich command-line utility that can easily be expanded by custom commands (Forkel et al. 2018, Forkel and List 2020) . Taking as an example the creation of a Nexus-file for phylogenetic analysis from an existing Lexibank Wordlist (List et al. 2022) , this tutorial will guide you through the necessary steps for writing a script that can be used as a CLDFBench command. You will then be able to apply the same workflow to other scripts you may want to use for a certain repository.
Querying Datasets with Cognates in the Lexibank Repository
Recently, I was asked by a colleague how one could query only those datasets in the Lexibank repository which come with cognate sets annotated by humans. While I first thought this could be done in a very straightforward way, I figeured out, when trying it myself, that the code still needs some workarounds. As a result, I thought it is best to share the solution I came up with in a blog post in order to make it accessible to colleagues who might be interested in inspecting and using the data provided by the Lexibank repository in more detail.
PyEDICTOR: A Small Python Package that Integrates LingPy, EDICTOR, and CLDF
With the introduction of CLDF as a major format for data exchange, there is an increased need in handy solutions for the conversion of CLDF to the formats required by computer-assisted tools like LingPy and EDICTOR, which allow to preprocess data automatically or to curate data by adding detailed annotations. With the publication PyEDICTOR, there is now a very lightweight software package that is supposed to provide first solutions for a successful integration of CLDF with these existing tools for computer-assisted language comparison.
How to Compute Colexification Networks with CL Toolkit (How to do X in Linguistics 11)
A colexification network is a network consisting of concepts as nodes with weighted edges drawn between the nodes, indicating how often the concepts colexify across the data in a given sample of languages. Having seen how individual colexifications can be computed with the help of the CL Toolkit package in an earlier blog post, we will now see how this code needs to be extended in order to compute colexification networks.
How to Compute Colexifications with CL Toolkit (How to do X in Linguistics 10)
Colleagues often ask us how they could receive more detailed information on specific languages and colexifications in the CLICS database. With the publication of the CL Toolkit package, which allows to merge several CLDF datasets on the fly, carrying out analyses on certain parts of the data underlying the CLICS database is now much easier than before. In order to illustrate this, this tutorial shows how colexifications for a selected number of languages can be computed from two distinct datasets that are included in CLICS (Version 3).
Blog Post Style Guide
The Computer Language Comparison in Practice blog has grown steadily over the past few years. Each year we had a number of blog posts written by our colleagues on various topics. With the introduction of a PDF copy for every blog post and the publication of an annual volume, these blog posts can be treated like publications in a non-peer-reviewed journal. We hope that our blog will continue to be a valuable publication venue for our colleagues, not only those working in our research group and department, but also outside collaborators, and scholars who are generally interested in the topic and want to share their ideas. To maintain a coherent structure for all posts, this blog post provides a style guide for all future posts. Continue reading
A Concept List for the Study of Semantic Extensions from Body to Objects
Many words have multiple meanings, especially words for body parts. Some languages call the branch of a tree arm and others refer to the roof with the word head. These are instances of colexifications between body and object concepts and they occur across various languages. However, languages vary in terms of the frequency of body~object colexifications in their lexicon. It is, therefore, important to understand the different drivers that can lead to body~object colexifications. One possible factor to consider is the degree of how visually conspicuous a part of the body is. In an ongoing project, I investigate the role of visual salience as a driving force behind body~object colexifications. This blog post gives a brief overview and introduces the concept list that is the basis for my study.

Extending the List of Color, Emotion, and Human Body Part Concepts
In a recent blogpost (Tjuka 2021), I introduced a list of color, emotion, and human body part concepts. The list is the basis for a study on colexifications across three semantic domains. The first version of the list included 192 concepts. Of these concepts, 34 were from the emotion domain. We decided to add 28 additional emotion concepts to the list because this will allow us to further improve our analysis and compare our results with previous studies on emotion semantics. This blog post introduces the extended list.
Converting Streitberg’s Gothic Dictionary to a CLDF Wordlist on a Windows System
I recently converted the Gothic dictionary written by Wilhelm Streitberg to a CLDF wordlist. Since I was using Windows, I had some difficulties during the conversion progress, which Unix system users may not have to deal with. I thought it would be useful to share my experience here and point out that users of Windows operating systems should be aware of certain aspects when converting data to CLDF.
