What does bore mean?
'Bore' is one of those rare English words that serves as both verb and noun across several distinct meanings. As a verb, it means either to pierce or hollow out material with a rotating tool — workers bore holes, tunnels, and wells — or, far more commonly in everyday speech, to weary someone through dullness: a monotonous speech bores its audience. The noun mirrors these senses, referring both to a person who tires others with tedium and, in technical contexts, to the inner diameter of a cylinder or gun barrel, or to a dramatic tidal surge up a river known as a tidal bore. The drilling sense descends directly from Old English 'borian'; the 'tedious person' sense appeared suddenly in the mid-1700s, its origin still debated by etymologists. Related forms include 'bored', 'boring', and 'boredom', making this a compact but versatile family of words essential to everyday expression.
To make a hole in or through something by drilling, digging, or turning a cylindrical tool; also, to weary someone by being dull or monotonous.
"The crew bored a tunnel straight through the mountain ridge."
The drilling sense typically takes a physical medium as direct object ('bore through rock'); the wearing sense usually takes a person ('bore the audience').
A tedious person or thing; also, the internal diameter of a tube, barrel, or cylinder; also, a steep tidal wave that advances up a river.
"At the party he proved to be an insufferable bore who talked only about himself."
In engineering and firearms, 'bore' refers specifically to interior diameter; in geography, 'tidal bore' names the wave phenomenon seen on rivers like the Severn and Qiantang.
Used when referring to multiple tedious people or things, or to multiple drilled openings/barrel diameters.
"The committee meeting was full of bores droning on about procedure."
Nobody is quite sure where 'bore' meaning 'tedious person' came from — it appeared out of nowhere in 18th-century conversation, making it one of English's etymological mysteries.

Etymology of bore
The verb meaning 'to pierce' comes from Old English 'borian', related to Old Norse 'bora' and ultimately to Proto-Germanic roots connected with drilling tools. The noun for the hole itself followed naturally from this sense. By contrast, the sense meaning 'to weary' or 'tedious person' first appears in written English around the mid-18th century, and its origin remains genuinely obscure — theories linking it to French 'bourde' ('nonsense') remain speculative. The tidal-bore noun may derive from Old Norse 'bára' ('wave'), though scholars have debated this too.

How bore is actually used
The word carries two distinct historical roots: the drilling sense comes from Old English 'borian', while the 'tedious person' sense emerged in the mid-18th century with an uncertain origin. The verb form is neutral in register, but calling a person a bore is mildly critical though not harsh — stronger than 'dull' but gentler than insults like 'drag'. The past tense of the drilling verb can be either 'bored' or the archaic 'bore', but modern usage strongly favors 'bored'.
