"nearest in place, position, rank, or turn," Middle English nexte, from Old English niehsta, nyhsta (West Saxon), nesta (Anglian) "nearest in position or distance, closest in kinship," superlative of neah (West Saxon), neh (Anglian) "nigh;" from Proto-Germanic *nekh- "near" + superlative suffix *-istaz. Cognate with Old Norse næstr, Dutch naast "next," Old High German nahisto "neighbor," German nächst "next."
In reference to time by c. 1200. Adverbial ("next to, immediately after; almost, within a little of") and prepositional ("nearest to, immediately adjacent to") uses are from c. 1200. Phrase the next man "a typical person" is from 1857. Next-best "second best" is by 1670s.
"near, nearby, close together, adjacent," Middle English neigh, from Old English neah (West Saxon, Kentish), neh (Anglian), from Proto-Germanic *naehwa- (source also of Old Saxon nah, Old Frisian nei, Middle Dutch, Dutch na, Old High German nah, German nah, Gothic nehwa), of uncertain origin, with no cognates outside Germanic. The Old English progression was neah - near - niehsta, for "nigh - nigher - nighest." But the comparative near and the superlative nehst (see next) gradually evolved into separate words that were no longer felt as related to nigh. New comparative and superlative forms nigher, nighest developed 14c. as phonetic changes obscured the original relationships. As an adjective and preposition in Middle English.
