"Unless ye believe ye shall not understand," may be thus resolved; "Ye believe; _dismiss_ (that fact) ye shall not understand." Or thus, "_Dismiss_ ye believe, (that circumstance being away) ye shall not understand." Thus by analizing the sentence we find no Subjunctive mode; but merely the Indicative and Imperative. "Kiss the Son, lest he be angry," is resolvable in the same manner: "Kiss the Son, _dismiss_ (that) he will be angry." _Else_ is used nearly in the same sense, as in Chaucer, Freres Tale, 7240: "Axe him thyself, if thou not trowest me, Or _elles_ stint a while and thou shalt see." That is, "If thou dost not believe me, ask him thyself, or _dismissing_ (omitting that) wait and thou shalt be convinced." _Though_, or _tho_, commonly called a conjunction, is also a verb in the Imperative Mode. It is from the verb _thafian_ or _thafigan_, which, in the Saxon, signified to _grant_ or _allow_. The word in its purity is _thaf_ or _thof_; and so it is pronounced by many of the common people in England, and by some in America. "_Tho_ he slay me, yet will I trust in him," may be thus explained; "_Allow_ (suppose) he should slay me, yet will I trust in him." That this is the true sense of _tho_, is evident from another fact. The old writers used _algife_ for _although_; and its meaning must be nearly the same. "----Whose pere is hard to find, _Algife_ England and France were thorow saught." Rel. An. Poet. 115. _Since_ is merely a participle of the old verb _seon_, to see. In ancient authors we find it variously written; as _sith_, _sithence_, _sin_, _sithen_, &c. and the common people in New England still pronounce it _sin_, _sen_ or _sence_. Of all these, _sin_ or _sen_, which is so much ridiculed as vulgar, comes nearest to the original _seen_.[89] This explanation of _since_ unfolds the true theory of languages, and proves that all words are originally derived from those which are first used to express ideas of sensible objects. Mankind, instead of that abstract sense which we annex to _since_, if we have any idea at all when we use it, originally said, _seen the sun rose, it has become warm_; that is, after the sun rose, or that circumstance being _seen_ or _past_. We use the same word now, with a little variation; but the etymology is lost to most people, who still employ the word for a precise purpose, intelligible to their hearers.
