Answer and explanation:
<u>A </u><u>simple subject</u><u> is the main word in the subject, the one that truly expresses the relationship with the verb. A c</u><u>omplete subject</u><u> is the main word plus all modifiers that appear in a subject.</u> Study the example below:
The tired, sweaty player passed out in the middle of the field.
Who passed out?
Simple subject: player
Complete subject: the tired, sweaty player
A predicate is the part of the sentence that tells us what the subject is or does. <u>A </u><u>simple predicate</u><u> consists of the verb or verb phrase. A </u><u>complete predicate</u><u> consists of the verb or verb phrase plus all the other words that are not part of the subject.</u> Study the example below:
The tired, sweaty player passed out in the middle of the field.
Simple predicate: passed out
Complete predicate: passed out in the middle of the field.
<u>A </u><u>compound sentence</u><u> is formed by joining two independent clauses connected by a coordinating conjunction - for, and, nor, but, or, yet, so. </u>Example: I went to school, but I didn't see my best friend there.
<u>A </u><u>complex sentence</u><u> is formed by joining an independent clause and a dependent one.</u> A dependent clause needs the independent one to give it context, so that it makes sense. It does not express a complete thought on its own. Example: I went to school because my mother made me.
<u>A </u><u>compound-complex sentence</u><u> is formed by two independent clauses and a dependent one, at least. </u>Example: Because my mother made me, I went to school; but I didn't see my best friend there.
