What is a noun phrase

A noun phrase, or nominal, is a phrase that has a noun as its head or performs the same grammatical function as a noun. Noun phrases are very common cross-linguistically, and they may be the most frequently occurring phrase type

Example:

Examples of noun phrase as direct object: I want a skate board. Should we buy the yellow house? Examples of noun phrase as object of preposition: Jeff rode on a skate board. Karen lives in the yellow house.
