REVISITING LEXEME BASED THEORY’S WORD FORMATION RULES; COUNTER EVIDENCE FROM URDU

The purpose of the current study is to evaluate the application of Lexeme Based Theory on Urdu language, because it claims to engulf, the all aspects of all languages, through its Word Formation Rules (WFRs). In this article, Urdu nouns and adjectives are carefully selected and scrutinized for the processing of these rules. This theory asserts to be universal, because of its rules and declares that morphology enjoys its autonomous position due to these principles, and it does not get crippled to be shouldered by syntax for the building up of meaning. Roots are idiosyncratic and diversification of meaning is confined within the territories of the root, even after inflection and derivation; semantic restriction Isomorphic attributes do not let the root astray from its original meaning. So, on the one hand this theory talks about the integrity of the word (mental lexicon) and on the other side, it says that “phrase like structure do not give unified meaning” Aronoff; 1976. and the word categories (Parts of Speech) never appear like a phrase. They never leave their lexical bases, thus follow No Phrase Constraint (NPC) strictly. This research analysis these two rules and poses these proceeding questions; if Urdu language follows the NPC rule and from where does the Urdu roots inherit their meanings. For this purpose, few of the nouns and adjectives were selected. They were authenticated by the native speakers' repertoire, and further their word categories and meanings were testified by consulting Urdu dictionaries. The results concluded that Urdu word formation, sometimes do not follow the NPC, thus put the lexical integrity of Aronoff (1976;2010) at stake. Secondly, Urdu language has many polysemic words and their meanings are not self-emergent, unless they are processe
