Glossary
Coordinators – a connector, such as and, but, or, yet, or so, joins one independent clause to another.
Paired Expression – includes a conjunction, which joins like (same word form) elements in a sentence, and a focusing adverb, which adds emphasis to one of the paired elements, such as either… or, not only… bu t (also).
Focusing adverb such as also, just, even, only mainly, mostly, particularly, especially, either…or, neither…nor, etc. emphasize a part of a clause. Focusing adverbs can modify noun phrases, prepositional phrases, verb phrases, adjective phrases and adverbial phrases. A focusing adverb is optional, that is, the sentence can be restated without the adverb, but there will be a loss of emphasis.
