The Hyphen (-)

139. Use the hyphen when a word must be divided at the end of a line.

Never divide words of one syllable, nor short words; such as, though, through, also, besides, over, etc.

Never divide words except at the end of a syllable, and always put the hyphen at the end of the first line, not at the beginning of the second.

Wrong division: int-end, prop-ose, superint-endent, expre-ssion.
Proper division: in-tend, pro-pose, superin-tendent, expres-sion.

In writing it is good usage not to divide a word like expression by placing ex on one line and the rest of the word on the next line.

140. Use the hyphen to divide certain compound words. No rule can be given by which to determine when compounded words demand the hyphen. Only custom determines.

Always use a hyphen with to-day, to-morrow, and to-night.
