A compound modifier (also called a compound adjective or a phrasal adjective or adjectival phrase) is a compound of two or more attributive words: That is, more than one word that together modify a noun. Compound modifiers are grammatically equivalent to single-word modifiers, and can be used in conjunction with other modifiers.
The constituent words of compound modifiers need not be adjectives; combinations of nouns, determiners, and other parts of speech are also common (man-eating and one-way).
The punctuation of compound modifiers in English depends on their grammatical role. Attributive compounds – modifiers within the noun phrase – are typically hyphenated, whereas the same compound used as a predicate will typically not be.

Famous quotes containing the word compound:
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
