A noun phrase is either a single noun or pronoun or a group of words containing a noun or a pronoun that function together as a noun or pronoun, as the subject or object of a verb. In grammar, a noun phrase (abberviated NP) is a phrase whose head is a noun or a pronoun, optionally accompanied by a modifier set. A word group with a noun or pronoun as its head. The noun head can be accompanied by modifiers, determiners (such as the, a, her), and/or complements. A NP most commonly function as a subject, object, or complement.  

 

Noun phrases normally consist of a head noun, which is optionally modified ("pre modified" if the modifier is placed before the noun; "post modified" if the modifier is placed after the noun). Possible modifiers include:  

• Determiners: Articles (the, a); demonstrative (this, that); numerals (two, five, etc.); possessives (my, their, etc.); and quantifiers (some, many, etc.). In English, determiners are usually placed before the noun.  

• Adjectives (the red ball); or (my little cat).  

• Complements, in the form of a prepositional phrase (such as: the student of physics), or a That-clause (the claim that the earth is around).

• Modifiers; pre-modifiers if placed before the noun and usually either as nouns (the university student) or adjectives (the beautiful lady), or post-modifiers if placed after the noun. A post modifier may be either a prepositional phrase (the man with long hair) or a relative clause (the house where I live). The difference between modifiers and complements is that complements complete the meaning of the noun; complements are necessary, whereas modifiers are optional because they just the give additional information about the noun.

Example of noun phrase:
- My coach is happy.
- I like the cars over there.
- The woman who lives there is my aunt.
- Frankenstein is the name of the scientist not the monster.
- I consider Tutdek my favorite cat.
- Small children often insist that they can do it by themselves.
- To read quickly and accurately is John's goal.
- Two of my guests have arrived.
-  Mr. Jones spoke to do Dr. James.
