Abstract
In recent years, there is an apparent increase in interest of linguists to do comparative studies on lexicology over the genetic and typologically related languages. This paper has sought to critically research the role of mutual lexical enrichment of kindred languages and assimilation of loanwords, in particular, anglicisms to the vitality, maintenance and revitalisation of Turkic languages in the age of globalisation. The most important reasons for penetration and use of words and terms borrowed from English in modern Turkic languages have extra linguistic nature. However, intra linguistic factors are not an exception. Owing to distinctions of graphic bases of the alphabets and pronunciation norms of Turkic languages, the level of phonetic, grammatical and semantic assimilation of loanwords and terms in these languages are not identical. Because of incomplete phonological and graphic adaptation of loanwords, it becomes clear that in the Turkic languages national colouring, phonetic and orthographic norms of these languages are partly changed. Keywords: Vitality, lexical system, Turkic languages, globalisation, anglicisms.
