Origin of bump
From American Heritage Dictionary of the English Language, 5th Edition
- From Early Modern English bump (“a shock, blow from a collision", also "to make a heavy, hollow sound, boom”), probably of North Germanic origin. Compare Danish bump (“a thump”), Danish bumpe (“to thump”), Old Danish bumpe (“to strike with a clenched fist”). Apparently related to Middle English bumben, bummen (“to make a hollow noise”), Dutch bommen (“to hum, buzz”), German bummen (“to hum, buzz”), Icelandic bumba (“drum”), probably of imitative origin. More at bum, bumble. Compare also bomb.
