1. Introduction

The expression Verb た ときに is used to indicate a specific time when something happened or a condition arose. It is commonly translated as "when (subject) did (action)" or "at the time when (action)". This structure is particularly useful for describing events in relation to other events or actions.

2. ときに, which means "when" or "at the time."

2. ときに: This phrase sets the time frame of when something occurs.

3. Comparative Analysis

Similar expressions include:

• Verb たら: This can also indicate a condition or time, but it is more conditional and can suggest "if" rather than just "when."
• Verb ているとき: This indicates an ongoing action: "when (action) is happening," which distinguishes it from the completed action of Verb た ときに.
