Abstract
Our objective in this paper is to clearly highlight the linguistic status of the copulative verb, especially with regard to the copula verb to be, with an eye on tracingthe influences of Logic on its approach as a syntactic entity and also on emphasizing the details that led to an eclectic definition. This epistemological approach aims at placing an emphasis on the subject of the diachronic and interdisciplinary copulative verb, in order to observe the way in which the conclusions from the level of the logical approach were transferred to the one of the linguistic approach and also to avoid the misuse of a series of concepts that were established either in a different domain or in the same domain, but at a different level. The main emphasis falls on defining the linguistic predicate through the grammatical tense.
