COMPOUND SUBJECT AND COMPOUND PREDICATE.
When two or more subjects united by a connecting word have the same predicate, they form a +Compound Subject;+ and, when two or more predicates connected in like manner have the same subject, they form a +Compound Predicate+.
In the sentence, Birds and bees can fly, the two words birds and bees, connected by and, have the same predicate; the same action is asserted of both birds and bees. In the sentence, Leaves fade and fall, two assertions are made of the same things. In the first sentence, birds and bees form the compound subject; and, in the second, fade and fall form the compound predicate.

+Explanation of the Diagram+.—The short line following the subject line represents the entire predicate, and is supposed to be continued in the three horizontal lines that follow, each of which represents one of the parts of the compound predicate. These three lines are united by dotted lines, which stand for the connecting words. The +X+ denotes that an and is understood.
