hyphen

n. Sign (-) used to join words semantically or syntactically (e.g. Fruit-tree, pick-me-up, rock-forming), to indicate the division of a word at the end of a line, or to indicate a missing or implied element (as in man- and womankind). v. = *hyphenate. [greek huphen together]

n. A mark or short dash, thus [-], placed at the end of a line which terminates with a syllable of a word, the remainder of which is carried to the next line; or between the parts of many a compound word; as in fine-leaved, clear-headed. It is also sometimes used to separate the syllables of words.
