Typological Characteristics of Existential Verbs and Tense-Aspect Markers

From the perspective of linguistic typology, this paper finds that Progressive and Continuous, and their related grammatical morphemes are mostly derived from existential verbs, including existential, copulative, possessive, displacement, residential and locative semantics.The linguistic phenomenon is cross-linguistically universal.On this basis, this paper investigates the evolution path and implicative universals of existential verbs and tense-aspect markers from the perspective of typology.It is found that mighty category characteristics of existential verbs, transformation from spatial domain to time domain, and semantic generalizations contribute to the progressive/continuous body markers evolving from existential verbs.
