Compound modifiers & compound nouns

http://en.wikipedia.org/wiki/Hyphen
The use of the hyphen in English compound nouns and verbs has, in general, been steadily declining.

Compound modifiers are groups of two or more words that jointly modify the meaning of another word.
When a compound modifier other than an adverb–adjective combination appears before a term, the compound modifier is often hyphenated to prevent misunderstanding, such as in American-football player or little-celebrated paintings.
