NP in linguistics means
noun phrase. The basic structure of a sentence may be symbolized in the
phrase structure rule S -> NP VP, where VP is the
verb phrase (sometimes called
predicate). An NP may contain other NPs, e.g. "
The Man Who Mistook His Wife for a Hat" is an NP (it can be used wherever "the man" is) containing a
relative clause, which is itself a
sentence with three NPs: subject "
who", object "his wife", and "a hat" within the prepositional phrase "for a hat". Likewise "
The Man with the Golden Gun" is an NP containing a
subordinate NP "the golden gun". It need not contain a
noun, but may be a
pronoun instead, since this functions the same way in the
syntax.
Np is the symbol for the element neptunium.
Also, Np is the symbol for the neper, a newly-invented (1998) SI unit for logarithmic quantities. A neper (named after John Neper or Napier) is dimensionally equal to one, and is such that e.g. 43 Np is e times larger than 42 Np.
