   • 2003 [1985], Eric Partridge, “Introduction to the First Editon”, in Paul Beale, editor, A Dictionary of Catch Phrases‎, 2nd edition, Routledge, →ISBN:

     Frequently, catch phrases are not, in the grammarians' sense, phrases at all, but sentences. Catch phrases, like the closely linked proverbial sayings, are self-contained, as, obviously, clichés are too. Catch phrases are usually more pointed and ‘human’ than clichés, although the former sometimes arises from, and often they generate, the latter. Occasionally, catch phrases stem from too famous quotations.
