Etymology

From Middle English bitte, bite, from Old English bita ("bit; fragment; morsel") and bite ("a bite; cut"), from Proto-Germanic bitô and bitiz, both ultimately from Proto-Indo-European bʰeyd- ("to split").

Cognate with West Frisian bit, Saterland Frisian Bit, Dutch bit, German Low German Beet and Biet, German Biss and Bissen, Danish bid, Swedish bit, Icelandic biti.

From Old English bāt, a strong past tense of bītan ("to bite"). Middle English retained this as bot, which was eventually displaced by the weak past form bit, modelled on the pattern of verbs like sit/sat. The older strong form survives only in fossilised use.

From binary digit, coined by John Tukey in 1946; the form was probably influenced by the existing sense of "small portion". Claude Shannon introduced it in print in 1948. Compare byte and nybble, which carry similar incidental food associations.
