Specifically I am wondering about the word "person" in the sentence, because at first thought I believed it was a common noun but it is qualifying a proper noun, so I am confused if it is a noun or a adjective. If it is a noun what kind of noun is it?
Amber = Subject of the sentence = (proper) noun.
is = verb of the sentence= (linking verb) verb.
a real person = object of the sentence = noun phrase, composed of:
- A = indefinite article= adjective
- real= adjective
- person = (common) noun = modified by: a and real, the head word of said noun phrase.
Ambar [Proper Noun] is a real person [Common Noun].
Other examples of Proper Noun; Pakistan, Islam, Muslim.
Other examples of Common Noun; bird, animal, student.
In "I am a Muslim.", notice that the word "Muslim" is a common term and gives a general sense of some religion. However, it is a Proper (and not Common) Noun.
