Etymology

intonation = in<into> + ton<tone> + ation<noun suffix>

  • in (Latin in-, "into") → Indicates direction or focus.
  • ton (Latin tonus, from Greek tonos, "tone, tension") → Refers to pitch or sound quality.
  • ation (Latin -atio, noun-forming suffix) → Denotes an action or result.

Etymology Origin:
The word intonation traces back to Latin intonare ("to thunder, resound"), combining in- (into) and tonare (to thunder). Over time, it shifted from literal sound projection to the nuanced modulation of voice pitch in speech and music. The morpheme ton preserves its Greek root tonos, reflecting the ancient link between tension (e.g., vocal cords) and pitch.
