Etymology

Origin of drum¹

First recorded in 1535–45; of uncertain origin; probably a back formation from drumslade “drum, drummer,” alteration of Dutch or Low German trommelslag “drumbeat,” equivalent to trommel “drum” + slag “a beat”; cognate with slay

Origin of drum²

First recorded in 1725–35; from Irish and Scots Gaelic druim, of unknown origin

Explanation

A drum is a musical instrument that you play by hitting it rhythmically with a stick or your hand. Most drums are round, with a thin material stretched tightly over the ends. Some drums, like the West African djembe, are played with bare hands by a drummer who plays just one drum at a time. Others are found in a drum kit, often part of a rock band or a jazz ensemble, which might include a bass drum, a snare drum, cymbals, and a tom-tom — or even more. The word drum is also a verb, meaning "to play a drum," and can also mean "a cylinder-shaped container."
