Discuss noun and noun phrase in Englisha detailed answer

A noun is a person, place, thing, or idea.  Words such as
boy, drum, house, bike, glory, are all examples of nouns.  A noun phrase is a bit more
complicated.  They are called noun phrases, because usually a noun or pronoun (I, you,
he, she, it, they, we, me, him, her, it, us, them) is at the head of the phrase. 
Usually, the noun or pronoun are with a set of modifiers.  There are different kinds of
modifiers: determiners, which are usually placed before the noun (this, that, the, five,
a, etc.); adjectives, such as colors; complements; and modifiers, which help to describe
the noun more--such as the handsome
man.

So, a noun phrase would look
like this:

The bold and the
beautiful...

The boisterous man
yelled...
