clitic

MORPHOLOGY/SYNTAX: element which, like affixes, cannot occur freely in syntax but is in need of a 'host'. A clitic can thus be regarded as a kind of bound morpheme. A typical clitic will attach itself to a host, that is, a (fully inflected) word or phrase. The observation that they can attach to inflected words distinguishes, among other things, clitics from affixes. Clitics come into two types: proclitics and enclitics. Proclitics attach themselves to the left of the host, while enclitics attach themselves to the right of the host. EXAMPLE: In French, object pronouns are clitics which are either proclitics, as me and les in (i), or enclitics, as les in (ii):

(i)   il	me	les	a	donnés	
      he	to-me	them	has	given
      'he has given them to me'
(ii)  donnez	-les	-moi				
      give	-them	-me
      'give them to me'

(iii) il mei lesj a donnés ei ej
