Obs. exc. dial. Forms: 67 battill, battell, batle, battle, 6 batel(l, 7 battel, 89 Sc. baittle, bettle. [For the etymology and mutual relations of this and the cognate BATTLE v.3, data are wanting; according to present evidence, the adj. appears earliest, being found in Scotch in 1513. Its form and sense agree with a derivation from *bat, representing ON. bati improvement, getting better, Du. baat improvement, advantage, profiting, profit, referred to under BATTEN v.1; with suffix as in brittle, bruckle, fickle, newfangle, and OE. etol, drincol, wittol. This would give as the primary sense given, tending, or fitted, to improve, better, fatten, etc. All the related words have a smack of Northern origin: battle or baittle grass is still common in south of Scotland.
The non-occurrence of bat, while its presumed derivatives, battle, battable, batful, batsome, are so frequent in 1617th c., is a difficulty; as is also the fact that batt-le, batt-able point to a verbal rather than a substantive base, and yet can hardly have been formed on batt-en.]
