sb. Obs. [OE. béot, contr. from earlier *bí·hát promise, the original noun-form, corresponding to the vb. bi-, be-há·tan: see BE-, BY-. For the contraction cf. héold (:he·-hald), béo, etc. A shifting of the stress from bí·hát to bi-há·t, on analogy of the vb., gave the late OE. behá·t, whence ME. BEHOTE, which is thus a doublet of béot.] A promise, vow, threat, boast.
