Word History

Etymology

earlier, "(of parts of the body) made up of one substance, homogeneous," borrowed from Medieval Latin similāris, from Latin similis "having characteristics in common, like" + -āris -ar; similis going back to dialectal Indo-European *sm̥h₂-el-i- (whence also, with different stem formations, Old Irish amal, preposition, "like, as," samail "likeness, similarity," Middle Welsh hafal "like, similar," Greek homalόs "even, uniform, equal, like"), derivative of *semh₂ "one, one and the same" — more at same entry 1

Note: Latin similis is presumably from *semilis, with e > i before a sonorant and a following i. Compare from the same stem simul "in company, together, at the same time" (semol in an early inscription), with i carried over from similis (see simultaneous); and semel "a single time, once" (see semelparous). — The Celtic outcomes show an internal change of *-ema- > *-ama- ("Joseph's Law"). The initial o in Greek homalόs, for expected *a, has probably been carried over from homόs "shared among all, common, same," homoîos "like, similar" (see homo- homeo-), — A different analysis of similis and like words has been proposed by G.E. Dunkel (Lexikon der indogermanischen Partikeln und Pronominalstämme, Heidelberg, 2014, p. 726). Behind similis the author sees *sm̥-h₂el-ó-, with *sm̥- as zero-grade of *som- "together, with, the same" and *h₂el- taken to be the verbal base meaning "nourish, bring up" (see old entry 1)—hence the compound would have meant "of equal growth," whence "like, similar." Dunkel analyzes semel "a single time," differently, however, as *sem-le, with *sem- "one" and *le "over there, distant" (pp. 491, 673).
