The following examples are based on the rules for compounding found in chapter 6. Obviously, this list or any other list of compound words could not possibly be a complete reference due to sheer volume. However, an analogy of the words listed with like prefixes and suffixes together with an application of the rules will result in easier handling of those compound words not listed.
In order to keep the list from becoming cumbersome, certain restrictions had to be adopted.
The listing of hyphenated compounds ending in ed was kept to a minimum. The rationale was to provide one or two examples under a keyword rather than needless repetition.
Similarly, many two-word forms which create no difficulty were omitted.
Care was exercised to achieve fuller coverage of solid compounds, particularly when the adopted form is different than that of Webster's Third New International Dictionary. This dictionary is GPO's guide for spelling with the exception of those words listed in rule 5.2. It is not GPO's guide to compounding.
A distinction exists between words used in a literal sense and a non-literal sense. With few exceptions, one-word forms usually express a nonliteral interpretation, while two-word forms invariably convey a literal meaning. For example, a person may have an interesting sideline or hobby, but be forced to sit on the side line during periods of inactivity.
Distinction should also be made in the compounding of two words to form an adjective modifier and the use of the same words as a predicate adjective; e.g., "crystal-clear water," but "the water is crystal clear"; "fire-tested material," but "the material is fire tested."
