PARAGRAPHING

Indention and Display are the methods employed in typography to secure clearness and to add distinction to the printed page, but clearness in the body of the text is dependent upon the skill of the writer in properly dividing his composition into paragraphs. Just as correct punctuation assists the reader in his understanding of a sentence, so does correct paragraphing add to the understanding of the composition as a whole. The following rules may be formulated, based upon the practice of the most careful writers:

1. A sentence which continues the topic of the sentence which precedes it rather than introduces a new topic should never begin a paragraph.

2. Each paragraph should possess a single central topic, to which all the statements in the paragraph should relate. The introduction of a single statement not so related to the central topic violates the unity.

3. A sentence or short passage may be detached from the paragraph to which it properly belongs if the writer wishes particularly to emphasize it.
