How to use 只有…才
只有 + necessary condition，subject + 才 + result
只有 introduces a condition presented as necessary for an outcome. The result cannot follow without that requirement, according to the speaker's statement. This makes the pattern useful for explaining restrictions, requirements, and what must change before progress is possible. It does not by itself promise that meeting the condition will automatically be sufficient in every real-world situation.
Put 才 in the result clause, after an explicit subject and before the predicate. The initial condition can be an action or a broader circumstance. Contrast 只有…才 with 只要…就: the former requires a condition, while the latter says that condition is enough. Bare 才 has other emphatic uses, so not every 才 sentence belongs to this pattern.
Examples with pinyin and English

What to remember
- Use 只有 to state a necessary requirement.
- Keep 才 in the result clause.
- Do not read every emphatic 才 as an only-if condition.
