Forms: also 7 baite, 79 bait, 89 bate. [Of doubtful phonetic form, and unknown origin. The modern Devonsh. pronunciation is (bēt), variously spelt bait, bate, beat. Although bait occurs constantly in Gervaise Markham, beat(e was the spelling of the vb. with Fitzherbert in 1534, Carew in 1602, and of the sb. with Worlidge in 1681, and is apparently the proper form. The vb. is found nearly a century before the sb., and may thus be its immediate source, but on general grounds, the converse is more likely.
The suggestion that beat is another form of PEAT, is incompatible with the history of the latter, q.v. The ON. beit pasturage, beiti pasture, also heath, ling, would barely do for the sense, and phonetically would give bait, not beat. See BEAT v.2]
