Clitic is the class of units which members exhibit syntactic characteristics of a lexical unit, but show evidence of being morphologically bound to another lexical unit, the host, by being unstressed or subject to word-level phonological rules [Crystal 1980, 64; Hartmann and Stork 1972, 38; Anderson 1985, 158; Klavans 1982, xi-xiv, 74-76,83,93-95,100-101; Zwicky 1977,5].
