Entries linking to near-sighted
Old English near "closer, nearer," comparative of neah, neh"nigh." Partially by the influence of Old Norse naer "near," it came to be used in English as a positive form mid-13c., and new comparative nearer developed in the 1500s (see nigh). Originally an adverb but now supplanted in most such senses by nearly; it has in turn supplanted correct nigh as an adjective.
