Origin & History of “bitter”

Old English biter appears to have come from *bit-, the short-vowel version of *bīt-, source of bite. Its original meaning would thus have been ‘biting’, and although there do not seem to be any traces of this left in the historical record, the sense development to ‘acrid-tasting’ is fairly straightforward (compare the similar case of sharp).

It seems likely that the bitter of ‘bitter end’ comes from a different source altogether, although in its current meaning it appears to have been influenced by the adjective bitter. A bitter was originally a ‘turn of a cable round the bitts’, and a bitt was a ‘post on the deck of a ship for fastening cables to’. It is not clear where bitt came from, although it was probably originally a seafarer’s term from the north German coast, and it may be related to English boat. Thus in the first instance ‘to the bitter end’ probably meant ‘to the very end, as far as it is possible to go’.
