RHYME, n. [Sax. rim, and gerim, number; riman, to number; ge-riman, id.; riman and ryman, to give place, to open a way, to make room; Sw. and Dan. rim; D. rym; G. reim; W. rhiv; Ir. rimh or reomh. The Welsh word is rendered also, that divides or separates, and the Sax. rim seems to be connected with room, from opening, spreading. The deduction of this word from the Greek ῥυθμος, is a palpable error. The true orthography is rime or ryme; but as rime is hoar-frost, and rhyme gives the true pronunciation, it may be convenient to continue the present orthography.]
