Etymology

siphon = siph<tube> + on<noun suffix>

  • siph: From Greek siphōn (tube, pipe), referring to a hollow structure for transferring liquids.
  • on: A noun-forming suffix in Greek, often retained in scientific or technical terms.

Etymology Origin:
The word siphon traces back to ancient Greek siphōn, meaning "tube" or "pipe." It entered Latin as sipho and later Old French as sifon, retaining its core meaning of a device for moving liquids. The modern spelling and usage reflect its scientific application, emphasizing gravity-driven fluid transfer. The morpheme siph preserves the original Greek root, while on acts as a neutral suffix, typical of borrowed technical terms.
