bore: Bore ‘make a hole’ [OE] and bore ‘be tiresome’ [18] are almost certainly two distinct words. The former comes ultimately from an Indo-European base *bhor-, *bhr-, which produced Latin forāre ‘bore’ (whence English foramen ‘small anatomical opening’), Greek phárynx, and prehistoric Germanic *borōn, from which we get bore (and German gets bohren). Bore connoting ‘tiresomeness’ suddenly appears on the scene as a sort of buzzword of the 1760s, from no known source; the explanation most commonly offered for its origin is that it is a figurative application of bore in the sense ‘pierce someone with ennui’, but that is not terribly convincing.
In its early noun use it meant what we would now call a ‘fit of boredom’. There is one other, rather rare English word bore – meaning ‘tidal wave in an estuary or river’ [17]. It may have come from Old Norse bára ‘wave’. => perforate, pharynx
