  • In the middle of doing something: an ongoing action or event that occurs before finishing.
  • Common collocations show progression or interruption along a path, such as 途中経過 or 途中下車.

Etymology

途 path, route; 由 reason, origin; together they form a Sino-Japanese compound whose pronunciation in common use is tochū, reflecting the notion of moving along a path and thus being in between start and end.

Composition

  • 途: path, route; contributes the sense of a journey or trajectory
  • 由: reason, origin; contributes to the idea of proceeding along a path toward a point

Usage

Used as a noun to denote being in the middle of a journey or process; can attach with particles, and forms phrases with 途中で to indicate something happening midway, and 途中経過 to refer to the current progress. In formal and casual speech it remains a standard noun; examples: 仕事の途中で電話が鳴った, バスの途中で降りる, 途中で道を聞く
💡 Tips
Mnemonic: imagine a traveler on a road (途) who keeps asking ‘why’ (由) about the next turn; you’re literally in the middle, Tochū, halfway there.
