An NP consists of a head, its complements, modifiers, and specifiers. The head is either a lexical element, or a complex structure. Complements are arguments of the head; they either are taken over from the verb, or are lexically specified. Modifiers can be prenominal or postnominal and will be marked as such. Specifiers can be determiners or quantifiers. The NP as a whole can be modified. In MT, in addition, we have to cope with terms (i. e. terminological units, consisting of several elements like nouns + PPs, ADJs + Nouns, etc.).
