只要 (as long as)

• Pinyin: zhǐyào
• Formation: 只要 + Condition，(就) + Result
• Hanzi breakdown: 只 = 口 (mouth) + 八 (eight/divide), 要 = 覀 (west/cover) + 女 (woman)

Meaning

The conjunction 只要 means 'as long as' or 'provided that,' introducing a sufficient condition. It is typically paired with 就 in the result clause to form the pattern 只要...就..., meaning 'as long as X, then Y.'

只要 presents a minimum or sufficient condition — if the condition is met, the result will follow. It differs from 只有...才... (only if), which presents a necessary condition. With 只要, the speaker implies that meeting the stated condition is enough to guarantee the outcome. 就 in the result clause can sometimes be omitted in casual speech, but including it makes the logical connection clearer. 只要 can also be used with negative conditions: 只要不迟到就行 (as long as you're not late, it's fine). This pattern is extremely useful for giving reassurance, making promises, or stating requirements.

Examples

1. 只要你努力学习，就一定能进步。 As long as you study hard, you will definitely make progress.
2. 只要天气好，我们就去公园。 As long as the weather is nice, we'll go to the park.
3. 只要坚持锻炼，身体就会越来越好。 As long as you keep exercising, your health will get better and better.
