|Description: A. Characterization of singular objects or events instead of giving a name. As opposed to names descriptions are not rigid, i.e. they may refer to different objects in different worlds. - B. Linguistic form for attributing predicates according to the perceptions of objects. See also rigidity, theory of descriptions.|

Description/Lewis: it always is also about the meaning of the terms used. - Therefore, it is pointless to point out several differences.

Definite Description/Lewis: necessary: something outstanding, relative prominence - not: uniqueness. - The prominence changes constantly during the conversation. - Denotation by a definite description then depends on the score keeping. - Alignment rule: Prominence of an object is affected by the course of the conversation. - Boundaries/Lewis: it is easier to expand the boundaries than to narrow them.
Failed descriptions are not meaningless. (Putnam: the theoretical terms of a refuted theory are meaningless.) LewisVsPutnam: they are not, if they are similar failed descriptions. "The Mars moon" and "The Venus moon" name nothing here in our real world (in any normal way); but they are not meaningless, because we know very well what they denote in certain other possible worlds.
