Etymology

To drill is inherited from Middle English boren, inherited from Old English borian (“to bore through, perforate”),[4][5][2] from bor (“auger”),[5] from Proto-Germanic *burōn,[4] cognate with Old High German borōn (modern German bohren) and Old Norse bora,[4][5][2][6] and related through Proto-Indo-European *bher- (“to cut”) to Latin forō (“to bore”) and feriō (“to strike”).[4][2][6]

Earliest recorded meaning

The verb: about 1000;[4] the noun, an auger, is Old English bor, from before 800.[4][5]

Semantic evolution

A hole made by boring is from about 1320,[7][5] the cylindrical cavity of a gun or tube from 1572, and its inner diameter, the calibre, from 1583.[7][5] A deep narrow hole bored into the earth is from 1674.[7] In Scots a blue bore was a gap in the clouds showing blue sky (1775).[7] Slang full bore, at top speed, is from 1936, from an unchoked carburettor.[5]

Borrowing
First attested

Borrowed from

Etymology

The wave is probably from an unrecorded *bore (“wave”), borrowed from Old Norse bára (“wave, billow”).[6][2][1]

Earliest recorded meaning

In Middle English a bore was any billow or wave; the modern sense dates from the early 17th century,[1] 1601 in Merriam-Webster.[6]

In the dialects of Worcestershire, Gloucestershire and Somerset the bore is the tidal wave of rivers such as the Severn and the Parrett.[8]

bore3 weary

Confidence
Unknown
First attested
1766

Etymology

To weary is of unknown origin.[4][2][1] Merriam-Webster suggests an alteration of obsolete bourd, to jest, from Middle French bourder.[6] Barnhart finds no evidence that it is a figurative use of the drilling bore, of persistent drilling or of “being in a deep hole”, as in the early phrase in a long bore.[4]

Earliest recorded meaning

As a noun, a fit of boredom or ennui, suggested to be a French malady: 1766.[4][2] The verb is from 1768.[4]

Semantic evolution

A tiresome person or thing is from 1778 in Barnhart;[4] Hoad dates the tiresome thing to the 18th century and the tiresome person to the 19th.[2] Boredom is from 1852, in Dickens's Bleak House.[4]
