Usage notes

Usage notes

The prefix non- may be joined to a word by means of a hyphen, which is standard in British usage. In many cases, especially in American usage, non- is joined without a hyphen, but a hyphen is preferred if its absence would obscure the understanding or pronunciation of the word. (For example, nonbaseball is relatively common, but noncricket — referring to a primarily British sport — is rare.) Some non- words rarely or never use a hyphen (such as nonentity). Unlike un-, non- tends to suggest an absolute negation without the possibility of shades of comparison. For example, more unkind sounds quite natural, but more nonhelpful does not. Meaning "not" in phrases taken from Latin and some other languages, non is a separate word and is not hyphenated. Examples: non compos mentis, persona non grata. As non- is a living prefix, the list of words having the prefix non- is practically unlimited. It is particularly common in the sciences. Non- may be attached to nouns, verbs, adjectives or adverbs to negate their meaning.
