Quiz: Remember the definition of mal de mer?
"flag material," 1742, perhaps from Middle English bonting gerundive of bonten "to sift," because cloth was used for sifting grain, via Old French, from Vulgar Latin *bonitare "to make good."
lark-like bird, c.1300, bountyng, of unknown origin. Perhaps from buntin "plump" (cf. baby bunting, also Scots buntin "short and thick;" Welsh bontin "rump," and bontinog "big-assed"), or a double diminutive of French bon. Or it might be named in reference to speckled plumage and be from an unrecorded Old English word akin to German bunt "speckled," Dutch bont.
