_Copulative_. And, if, that, both, then, since, for, because, therefore,
wherefore, provided, besides.
_Disjunctive_. But, or, nor, as, than, lest, though, unless, either,
neither, yet, notwithstanding, nevertheless, except, whether, whereas,
as well as.
Some conjunctions are followed by corresponding conjunctions, so that,
in the subsequent member of the sentence, the latter answers to the
former; as,
1. _Though_--_yet_ or _nevertheless_; as, "_Though_ he was rich, _yet_
for our sakes he became poor."
2. _Whether_--_or_; as, "_Whether_ he will go, _or_ not, I cannot tell."
It is improper to say, "Whether he will go or _no_."
