to its *object* (*sign-dynamic object* relationship), and (3) its relation to its *interpretant* (*sign-final interpretant*) (ibid.).

It was Jakobson who introduced Peirce's *icon/index/symbol* triad (part of the sign-object relationship) into modern linguistic theory. Through this triad, Peircean semiotic theory became widely known in linguistics and was applied in works that demonstrated the significance of the non-arbitrariness of the linguistic sign [1]. Non-arbitrariness must be understood as a relative phenomenon, not an absolute, and is particularly powerful at the phonological, morphological, and morphophonemic levels in languages. Much later, sociolinguistics and identity studies borrowed the terminology as well but with changes (cf. [14]).
