- monotony (n.)
- 1706, originally in transferred sense of "wearisome, tiresome," from French monotonie (1670s), from Greek monotonia "sameness of tone, monotony," from monotonos "monotonous, of one tone," from monos "single, alone" (see mono-) + tonos "tone" (see tenet). Literal sense of "sameness of tone or pitch" in English is from 1724.
