Adjectives can be compounded:
They love their tan and white kitten.
And so can adverbs:
Geoffrey quickly and quietly cleaned his room.
Similarly, subjects, verbs, and complements can all be compounded:
Note that "either ... or..." and "neither ... nor...." are variations of "or," and thus also function as coordinating conjunctions:
Neither Bill nor Tom likes either swimming (DO) or fishing (DO).
Simply remember that any type of grammatical construction may be compounded.
