Understanding the key differences between 再 and 才 when both mean “not until” – one for sequence, one for conditions/lateness
1 Key Concept: “Not Until” with Different Meanings
Both 再 (zài) and 才 (cái) can have the meaning of “not until” in English. However, there is a significant difference in their usage:
- 再 (zài) is used when making a suggestion, request, or giving commands. It stresses the order of events – one thing should happen before another.
- 才 (cái) when used to mean “not until” implies either later than anticipated, or a condition that must first be fulfilled.
The key distinction is that 再 focuses on sequence while 才 focuses on conditions or lateness.
