Syllabification

In the New Oxford American Dictionary, syllable breaks are shown for main entries and derivatives. Although all possible breaks are shown, there are some conven- tions that govern how writers break words at the ends of lines. Guidelines include:

Avoid a break that will leave one letter and a hyphen at the end of the line or one letter (or one letter and a punctuation mark such as a period) at the beginning of a line.

Avoid breaking a word that is already hyphenated except at that hyphen (e.g., self-affirmation; leather-bound).

Never break proper names.

Avoid breaking abbreviations.
