Word History

Etymology

Verb (1)

Middle English boren, going back to Old English borian, going back to Germanic *bur-ō- (whence Old High German borōn "to pierce," Old Norse bora), probably verbal derivative of a noun base bur- "tool for piercing" (whence Old English bor "chiseling instrument," Old High German bora); akin to Latin forāre "to bore," ferīre "to strike"

Noun (1)

Middle English, "hole, perforation," in part noun derivative of boren "to bore entry 1," in part borrowed from Old Norse bora "borehole," derivative of bora "to bore"

Noun (2)

Middle English *bore wave, from Old Norse bāra

Noun (3)

of uncertain origin

Note: Plausibly a derivative of the verb bore entry 6, if this was a sense development of bore entry 1 ("to drill, wear at" & "to induce ennui"); however, the noun, a vogue word among London political and cultural figures in the 1760's, appears to predate the verb.

Verb

perhaps verbal derivative of bore entry 5 if the noun is earlier

Note: See note at bore entry 5.
