Appendix G Compound Words

G.1 Use the Gregg Reference Manual, latest Webster's dictionary, and GPO Style Manual as references for compounding words. As you will notice, certain words are illustrated differently in various sources. In these cases, defer to the more commonly used version.

G.2 Word forms are constantly changing. Two-word forms often require the hyphen initially, then later become one word. Current language trends point to closing up words which, through frequent use, have become associated in the reader's mind as units of thought.

G.3 Generally, whenever a word form (or applicable rule) cannot be found in the Gregg Reference Manual, GPO Style Manual, or dictionary, it should be two words.

G.4 The following represents commonly used compound words. The abbreviations indicate function: noun (n.), adjective (adj.), verb (v.), adverb (adv.). Keep in mind that many words can function as different parts of speech, depending on the context. Most hyphenated words require hyphens if they precede the word they're describing, but they are usually written without hyphens if they follow the described word. This listing is a representation of commonly used words at NASA. It is not intended to be an inclusive listing.
