Etymology: The word "oscillator" is built from "oscillate" plus the agent suffix "-or", which turns a verb into a noun for the thing or person that performs the action. "Oscillate" comes from Latin "oscillare", meaning to swing or move back and forth, and that root gave English a precise physical picture: something swinging like a child's swing or a pendulum. The suffix has a longer road. It descends from Latin "-tor", which passed through Old French "-eor" and Middle English "-our" before settling into the modern English "-or" spelling, the same ending found in words like "actor" and "doctor". Attaching it to a verb meaning "swing" produced a noun for whatever swings or repeats its motion on its own.
