The important turn that generative grammar has adopted in relation to the so called Minimalist Program and its features theory have motivated the choice of this area of theory. In synthesis, this theory proposes that every linguistic object is defined for a grammatical features set. We take up the equivalence hypothesis between the structures' projected conditions and the projector core features. And we eventually establish the relevant features in the syntactic structures condition and its projection process. %K syntactic structure %K thematic structure %K sentence %K feature %U http://www.sintagma-online.udl.cat/imatges/pdf/2007a.pdf
