There are no precise rules, so the following are brief guidelines
1 When two short nouns are joined together, they form one word without a hyphen (a teacup) We do not join two short nouns if this leads to problems of recognition bus stop (Not "busstop*)
2 Hyphens are often used for verb + particle combinations (make up) [> App 31.35] and self combinations (self-respect)
3 When a compound is accepted as a single word (e g it has an entry in a dictionary) the tendency is to write it as one word (sunbathing) In other cases, the use of the hyphen is at the discretion of the writer (writing paper or writing paper), but the tendency is to avoid hyphens where possible
