ects sentences, is not a conjunction, but a conjunctive adverb.
_Provided_, as cited above, resembles not the verb, but the perfect
participle. _Either_ and _neither_, when they are not conjunctions, are
pronominal adjectives, rather than pronouns. And, to say, that, "words
_belonging to other parts of speech_, are used as _conjunctions_," is a
sort of solecism, which leaves the learner in doubt to what class they
_really_ belong. _Being_, and _being that_, were formerly used in the sense
of _because, since, or seeing that_; (Lat. _cum, quoniam_, or _quando_;)
but this usage is now obsolete. So there is an uncommon or obsolete use of
_without_, in the sense of _unless_, or _except_; (Lat. _nisi_;) as, "He
cannot rise _without_ he be helped." _Walker's Particles_, p. 425. "Non
potest _nisi_ adjutus exsurgere."--_Seneca._

CLASSES.

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_.

I. 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."

II. 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._

III. 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.

OBS.--Not all terms which stand in the relation of correspondents, or
corresponsives, are therefore to be reckoned _conjunctions_; nor are both
words in each pair always of the same part of speech: some are adverbs; one
or two are adjectives; and sometimes a conjunction answers to a preceding
adverb. But, if a word is seen to be the mere precursor, index,
introductory sign, or counterpart, of a conjunction, and has no relation or
import which should fix it in any other of the ten classes called parts of
speech, it is, clearly, a conjunction,--a _corresponding_ or
_corresponsive_ conjunction. It is a word used _preparatively_, "to connect
words or sentences in construction, and to show the dependence of the terms
