The theory claims that in all natural languages, the major lexical categories, that is, nouns, verbs, adjectives and prepositions have similar complement structures and levels of projection. 'l'he study shows that verbs in this language take A' ", N" " P'" and CPs at V'; VPadverbials at V" ; and parentheticals at V" '. This is consistent with the claim of the theory. The position of the head in relation to its complement is always final which fixes the parameter of Awiogi as a head-final languageenThe theory claims that in all natural languagesThesis
