Among some controversial issues in relation to the territory of linguistics, archetype notion of lexicalization-grammaticalization in cognitive grammar and etymological method were discussed as examples of comparison. The notion of archetype (or prototype) has no empirical ground to be treated as basic notion at the categories of lexicon and grammar. It is more empirical to suppose
that the schematization of conceptualization and the process of lexicalization-grammaticalization belong to different levels. The notion of archetype in the process of conceptualization is repeated
at the level of lexicalization-grammaticalization: from source domain of a concept to target domain. A semantic network of an individual is always bound to develop itself from initial stage: in a figurative sense it could be called ‘initialization’.
The origin of the concept of prototype and the source concept at lexicalization are as below. The first, it comes from the sensory experiences. In the case that a source of experience is changed, the concept of prototype itself changes, too. The prototype is not unchangeable, but variable according
to environment being cognized by language user. It resembles the formation process of dialect areas. As if dialect area is divided and re-formed by language contacts, prototype concept is reformed by influences of environments. The second is a re-construction of prototype by acquisition.It is made up or re-formed by etymological analysis as mentioned before or language learning within influences of school and mass media. The causes of linguistic changes could be explained such a way that the cognitive mechanism of language acquisition always requires initialization or reset of linguistic ability. Therefore the present aim of linguistic study needs to investigate the mechanism of language and to co-operate with other sciences.
