### Etymology 1

From Early Modern English bump (“a shock, blow from a collision”), probably of North Germanic origin; compare Danish bump (“a thump”), Danish bumpe (“to thump”), Old Danish bumpe (“to strike with a clenched fist”), all probably of imitative origin.
Apparently related to Middle English bumben, bummen (“to make a hollow noise”), Dutch bommen (“to hum, buzz”), German Low German bumsen (“to bump, push”), German bummen (“to hum, buzz”), Icelandic bumba (“drum”). More at bum, bumble. Compare also bomb.
