6. Compounding Rules
(See also Chapter 7 “Compounding Examples”)
6.1. A compound word is a union of two or more words, either with
or without a hyphen. It conveys a unit idea that is not as clearly or
quickly conveyed by the component words in unconnected succes-
sion. e hyphen is a mark of punctuation that not only unites but
also separates the component words; it facilitates understanding,
aids readability, and ensures correct pronunciation. When com-
pound words must be divided at the end of a line, such division
should be made leaving pre xes and combining forms of more than
one syllable intact.
6.2. In applying the rules in this chapter and in using the list of ex-
amples in the following chapter, “Compounding Examples,” the
uid nature of our language should be kept in mind. Word forms
constantly undergo modi cation. Although it is o en the case that
hyphenated compound words eventually lose their hyphen, many
of them start out unhyphenated.
6.3. e rules, therefore, are somewhat exible. Exceptions must nec-
essarily be allowed. Current language trends continue to point to
closing up certain words which, through either frequent use or
widespread dissemination through modern media exposure, have
become xed in the reader’s mind as units of thought. e tendency
to merge two short words continues to be a natural progression to-
ward better communication.
General rules
6.4. In general, omit the hyphen when words appear in regular order
and the omission causes no ambiguity in sense or sound.
