sentences:  In some variants of the Minimalist Program Merge is triggered by feature checking, e.g.the verb "eat" selects the noun "cheesecake" because the verb has an uninterpretable N-feature [uN] ("u" stands for "uninterpretable"), which must be checked (or deleted) due to full interpretation.By saying that this verb has a nominal uninterpretable feature, we rule out such ungrammatical constructions as *eat beautiful (the verb selects an adjective).
