You see that short statements closely related in meaning may be improved by
being combined. But young writers frequently use too many _ands_ and other
connectives, and make their sentences too long.

Long sentences should be broken up into short ones when the relations of
the parts are not clear.

As clauses may be joined to form sentences, so sentences may be united to
make _paragraphs_.

A +_paragraph_+ is a sentence or a group of related sentences developing
one point or one division of a general subject.

The first word of a paragraph should begin a new line, and should be
written a little farther to the right than the first words of other lines.
