From Middle French, from Old French buison, boissun (“stand of wild shrubs”), diminutive of Old French bois, bosc (“area planted with trees”), from Frankish *bosk, *busk (“bush”), from Proto-Germanic *buskaz (“bush, thicket”), perhaps from Proto-Indo-European *bʰuH- (“to grow”). Cognate with Old Norse buskr (“bush”), Middle High German busch, bosch (“bush”), Middle English busshe. More at bush; bois + -on.
