It is not possible to specify firm rules for hyphenation, except that the primary function of the hyphen is to indicate that two or more words are to be read together as a single word having one meaning. Hyphens should be avoided if possible. So, for example, making composite words (q.v.) may be acceptable. Composite adjectives usually are hyphenated to clarify meaning. They may be formed from two adjectives (red-hot), adjective or adverb plus participle (easy-going, well-developed), adjective plus noun (short-term), noun plus participle (weight-bearing), or verb plus adverb (made-up). Consider the effect of leaving out or moving the hyphens in the following: very fine-grained sediment; a hard-working woman; a man-eating polar bear; two-year-old horses; a submarine-cable-laying ship; a room in the hotel reserved for hunting-guests.
