English

Pronunciation

  • IPA(key): /ˈnɒn/

Prefix

non-

  1. Used in the sense of not, to negate the meaning of the word to which it is prefixed.
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. (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). By contrast, un- is almost always spelled without a hyphen.
  • Unlike un-, non- tends to suggest an absolute negation without the possibility of shades of comparison. For example, very unhelpful is common, but very nonhelpful is not.
  • Meaning "not" in phrases taken from Latin and some other languages, non is a separate word and is not hyphenated: 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.
