只要…就【zhǐyào … jiù】

只要…就 says the condition is enough: meet it, and the result follows. 只要 opens the condition, and 就 goes before the verb of the result, after its subject.

The condition is often something small or easy, which is the point: that's all it takes.

就 goes after the subject

• × 只要你来，就我很高兴 → 只要你来，我就很高兴

只要…就 or 只有…才

只要 says the condition is enough; there may be other ways to the same result. 只有…才 says it is the only way. Side by side:

• × 只要多听，才能听懂 → 只要多听，就能听懂
