[spiros]

Non- may be attached to nouns, verbs, adjectives or adverbs.
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.
