=Correlatives=

Conjunctions that are used in pairs are called correlatives; for
example, _not only_ ... _but also_ ..., _both_ ... _and_
..., _either_ ... _or_ ..., _neither_ ... _nor_ ..., _not_ ... _or_ ...,
_whether_ ... _or_ ....

=31. Correlatives should usually be followed by elements parallel in
form; if a predicate follows one, a predicate should follow the other;
if a prepositional phrase follows one, a prepositional phrase should
follow the other; and so on.=
