A Conjunction is a word used to connect words or sentences in construction, and to show the dependence of the terms so connected: as,

"Thou and he are happy, because you are good."--Murray.

Conjunctions are divided into two general classes, copulative and disjunctive; and a few of each class are particularly distinguished from the rest, as being corresponsive.

A copulative conjunction is a conjunction that denotes an addition, a cause, a consequence, or a supposition: as,

"He and I shall not dispute; for, if he has any choice, I shall readily grant it."

A disjunctive conjunction is a conjunction that denotes opposition of meaning: as,

"Though he were dead, yet shall he live."--St. John's Gospel.

"Be not faithless, but believing."--Id.

The corresponsive conjunctions are those which are used in pairs, so that one refers or answers to the other: as,

"John came neither eating nor drinking."--Matt., xi, 18.

"But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you."--Ib., xii, 28.

The Copulatives; And, as, both, because, even, for, if, that, then, since, seeing, so.

The Disjunctives; Or, nor, either, neither, than, though, although, yet, but, except, whether, lest, unless, save, provided, notwithstanding, whereas.

The Corresponsives; Both--and; as--as; as--so; if--then; either--or; neither--nor; whether--or; though, or although--yet.
