The division of words at the ends of lines is always undesirable, but many cases occur where such divisions are unavoidable. Certain rules governing divisions should never be broken, while others are desirable but may be broken when good spacing demands it. In this chapter, therefore, rules marked with an dagger are subordinate to the rules of good spacing.
Good taste proscribes any division that is misleading as to meaning or pronunciation.
Divide on a vowel wherever practicable. In case a vowel alone forms a syllable in the middle of a word, run it into the first line. Do not except in extreme cases divide on a syllable with a silent vowel, or carry over a syllable of two letters. One-letter divisions are never permissible. Except in extreme cases do not divide sums of money or other numbers expressed in figures.
