When a language colexifies several concepts, this is generally understood as a sign that these concepts are semantically related.[1] Research in lexical typology has thus been using colexification as a tool to measure semantic similarity between concepts.[2]
Definition
Colexification describes the case of different meanings being expressed by the same word (i.e., "co-lexified") in a language. For example, the two senses which are distinguished in English as people and village are colexified in Spanish, which uses pueblo in both cases.[3]
The opposite of "co-lexify" is "dis-lexify", i.e. 'express two meanings using different lexical forms'.[6] Thus, Russian colexifies 'arm' and 'hand' using the single word рука, but Spanish dislexifies these two meanings using two distinct words, respectively brazo v. mano.
The term was coined by the linguist Alexandre François in his 2008 article "Semantic maps and the typology of colexification". This article illustrated the notion with various examples, including the semantic domains of {STRAIGHT}, {CALL}, {BREATHE}. The latter notion is at the source of a colexification network that is attested in several languages, linking together such senses as 'breath', 'life', 'soul', 'spirit', 'ghost'...: Sanskritआत्मन्ātmán; Ancient Greekψυχή, πνεῦμα; Latinanimus, spīritus; Arabicروحrūḥ, etc. François built on that example to propose a method for constructing lexical semantic maps.
Several studies have taken up the concept of colexification and applied it to different semantic domains and various language families.[8]
Colexification is also the object of a dedicated database, known as CLiCS "Database of Cross-Linguistic Colexifications".[9] Based on data from more than 2400 language varieties of the world, the database makes it possible to check the typological frequency of individual instances of colexification,[10] and to visualize semantic networks[11] based on empirical data from the world's languages.
↑ The only exception would be cases of homophony, when two semantically unrelated words sound (or look) identical for accidental reasons. Homophony is not central to the study of colexification.
