§223. Conjunctions

Conjunctions connect words, phrases, or sentences. They are of two classes, Coördinate and Subordinate:—

a. Coördinate, connecting coördinate or similar constructions (see § 278. 2. a). These are:—

• Copulative or disjunctive, implying a connection or separation of thought as well as of words: as, et, and; aut, or; neque, nor.
• Adversative, implying a connection of words, but a contrast in thought: as, sed, but.
• Causal, introducing a cause or reason: as, nam, for.
• Illative, denoting an inference: as, igitur, therefore.

b. Subordinate, connecting a subordinate or independent clause with that on which it depends (see § 278. 2. b). These are:—

• Conditional, denoting a condition or hypothesis: as, sī, if; nisi, unless.
• Comparative, implying comparison as well as condition: as, ac sī, as if.
• Concessive, denoting a concession or admission: as, quamquam, although (lit. however much it may be true that, etc.).
• Temporal: as, postquam, after.
• Consecutive, expressing result: as, ut, so that.
• Final, expressing purpose: as, ut, in order that; nē, that not.
• Causal, expressing cause: as, quia, because.
