Concerning the history, formulation and interpretation of the conversion’s issue in english language

This paper examines history of formation, formulation and the process of conversion in English in the context of Functional Discourse Grammar. Although conversion has traditionally been considered to be morphological in nature (zero-derivation), different authors have suggested a syntactic approach, in which lexemes are deprived of categorial information in the lexicon and are put to use in different syntactic contexts and this  article comprises proper scientific analysis and methodological description of various linguists’ approaches concerning this quite a controversary and complicated linguistic issue of conversion.
