The grammaticalization of the existential sign var in Turkish Sign Language: a Construction Grammar approach

Abstract

Abstract This paper describes the development of the existential sign var ‘there’ in Turkish Sign Language from a synchronic point of view. The sign has been previously described as being restricted to clause-final predicate position and typically used for two main linguistic functions: (i) existential and (ii) possessive. However, abundant corpus evidence indicates that var can also be used for other linguistic functions in post-verbal position, which have not been reported in the literature before. Following Construction Grammar, this study presents a theoretical framework to investigate how the construction [verb + var] arose and what its semantic motivation is, paying particular attention to the notion of possession. It is argued that this construction has three different functions: (i) habitual, (ii) evidential, and (iii) assumptive. According to this account, var originated as an existential marker and subsequently developed into a marker of possession, before evolving to encompass its other linguistic functions in three stages. Using Labov’s Apparent Time Hypothesis (Labov, William. 1963. The social motivation of a sound change. Word 19(3). 273–309), closer examination also revealed that a progressive difference exists between age groups. Younger TİD signers use the construction [verb + var] more frequently, and as the age of the TİD signer decreases, the usage of this construction in the assumptive function increases considerably.
