Introducing English Linguistics

Coming out of the libraries

conjoining only two clauses.
While it is clear in the preceding examples that “like” units are coordi-
nated, in some cases this notion becomes problematic. For instance, in the
example below, two noun phrases are conjoined. However, the first noun

contains both a forename and surname: Dweezil Zappa.

(1981: 203—7) argues that in the first conjoin of this example, the surname
is “latent”; that is, its existence in this noun phrase is implied so that what
is really coordinated is something like:
