1.
each time; every time; on each occasion
Refers to every instance or occurrence of something. Almost always appears in the pattern その都度 (on each occasion) or verb+都度 (each time something happens).
都度 almost always appears in fixed patterns rather than being used independently.
Common patterns
- その都度 (on each occasion, every time)
- [verb]たびに、その都度 (each time [verb] happens)
- 必要な都度 (whenever necessary)
- [noun]の都度 (on each occasion of)
The pattern その都度 is by far the most common usage. It emphasizes responding to situations individually as they occur, rather than having a single fixed approach. Common in business and formal writing, but also used in everyday speech.
