To form a complete sentence, two main parts must be present:
a subject and a predicate.
A subject is what or who the sentence is about while
a predicate describes what the subject is or is doing. For example
consider the sentence:
Ron went to the mall.
In the above sentence, "Ron" is the subject
because the sentence is about Ron. The rest of the sentence "went to the
mall" is the predicate, because it describes what Ron did. The subject of
a sentence is usually the main noun or pronoun while the predicate is the verb
and its modifiers in the sentence.
There are two different classifications of subject and
predicate.
1. Simple
vs. complete subject or predicate
2. Compound
(vs. singular) subject or predicate
