早い describes an early time; 遅い can describe a late time or slow movement.
The idea
For time, 早い contrasts with 遅い: 早く起きます means “get up early”, 遅く着きました means “arrived late”. For speed, 速い is the usual spelling for “fast”, and 遅い can mean “slow”. The adverbs 早く and 遅く modify verbs.
| Form | Example |
|---|---|
| 早い | 早い時間 |
| 遅い | 遅く着きます |
| 速い | 電車が速い |
