只要/只有…才…: only if/unless
Two different conditional patterns — choose carefully:
| Pattern | Meaning | Result word |
|---------|---------|-------------|
| 只要 + condition + 就 | as long as (sufficient condition) | 就 |
| 只有 + condition + 才 | only if / only by (necessary condition) | 才 |
✅ 只要你努力，就一定能学好。(Effort is enough — sufficient)
✅ 只有坚持练习，才能真正提高。(Practice is the ONLY way — necessary)
Contrast: 只要/就 = one way among many; 只有/才 = this is the sole path.
