nonsuch (n.)

Middle English non, none, from Old English nan "not one, not any, no person; not the least part," from ne "not" (see no) + an "one" (see one). Cognate with Old Saxon, Middle Low German nen, Old Norse neinn, Middle Dutch, Dutch neen, Old High German, German nein "no," and analogous to Latin non- (see non-). It is thus the negative of one, an, and a (1).

As an adverb, "1650s, "by no means;" 1799 as "in no respect or degree, to no extent." As an adjective from late Old English; since c. 1600 reduced to no except in a few archaic phrases, especially before vowels, such as none other, none the worse.

c. 1200, Old English swylc, swilc "just as, as, in like manner; as if, as though; such a one, he" (pronoun and adjective), from a Proto-Germanic compound *swalikaz "so formed" (source also of Old Saxon sulik, Old Norse slikr, Old Frisian selik, Middle Dutch selc, Dutch zulk, Old High German sulih, German solch, Gothic swaleiks), from swa "so" (see so) + *likan "form," source of Old English gelic "similar" (see like (adj.)). Colloquial suchlike (early 15c.) is pleonastic.
