Etymology

Origin of metronome

1810–20; metro- 1 + -nome < Greek nómos rule, law

Explanation

Remember that little pyramid-shaped machine with the pendulum that clicked so agonizingly during your early piano lessons? Well, that was a metronome, a device that helps musicians keep to the tempo of the music. The metronome was invented in 1815 by a German engineer called Johann Maelzel, who was good friends with Beethoven. They even performed together, with Maelzel giving demonstrations of his device in the intervals. The metronome has come in for some criticism, but if it was good enough for Beethoven, it's probably good enough for you. The name comes from the Greek words metron for "measure," and nomus for "regulating."
