Structure of Sentences
According to certain features of their structure, sentences are classified as simple, compound, or complex.
A simple sentence is one consisting of a single clause or assertion.
Time flies.
Time came and went.
Time and tide wait for no man.
Men and women laughed and cried.
The subject of a simple sentence may consist of one noun or pronoun with its modifiers, or of two or more nouns with their modifiers. In the latter case, the subject is called a compound subject. Similarly, the predicate may contain one verb or two or more verbs. Occasionally a sentence will have a compound subject and a compound predicate, as in the last example given.
