"ingenuous, artless, natural," 1590s, from French naïf, literally "naive" (see naive). The masculine form of the French word, but used in English without reference to gender. As a noun, "natural, artless, naive person," first attested 1893, from French, where Old French naif also meant "native inhabitant; simpleton, natural fool."
"a v-shaped nick or indentation," 1570s, probably a misdivision of an otch (see N for other examples), from French oche "notch," from Old French ochier "to notch," a word of unknown origin. Said to be unconnected to nock. U.S. meaning "narrow defile or passage between mountains" is from 1718, mostly a New England and New York word for what is called further south a gap.
place in Yorkshire, earlier Scarðabork, etc., apparently a viking name, from Old Norse and meaning "fortified place of (a man called) Skarthi," who is identified in old chronicles as Thorgils Skarthi, literally "Thorgils Harelip," from Old Norse skartð "notch, hack (in the edge of a thing); mountain pass." It has been noted that a literal reading of the name as "gap-hill" suits the location. Scarborough warning "short notice or none" is from 1540s.
The neuter genitive pronoun in Middle English was his, but the clash between grammatical gender and sexual gender, or else the application of the word to both human and non-human subjects, evidently made users uncomfortable. Restriction of his to the masculine and avoidance of it as a neuter pronoun is evidenced in Middle English, and of it and thereof (as in KJV) were used for the neuter possessive. In literary use, his as a neuter pronoun continued into the 17c. In Middle English, simple it sometimes was used as a neuter possessive pronoun (c. 1300).
