只有 (zhǐyǒu) means "only if," and is used with 才 (cái) to emphasize that only one course of action will bring about the desired outcome.

Structure

只有 + Essential Condition + 才 (能) + Desired Outcome

Note that 才 is often followed by 能, but not always. This pattern is usually used for hypothetical situations, and is used what is in logic called a "necessary and sufficient condition," meaning "if and only if...."

Examples

  • 只有 努力 能 做 好 工作。Zhǐyǒu nǔlì cái néng zuò hǎo gōngzuò.Only if you work hard is it possible to do a good job.
  • 只有 多 吃饭 能 长高。Zhǐyǒu duō chīfàn cái néng zhǎng gāo.Only if you eat more will you be able to grow tall.
  • 只有 多 说,你的 中文 会 提高。Zhǐyǒu duō shuō, nǐ de Zhōngwén cái huì tígāo.Only if you speak more will your Chinese improve.
  • 只有 大家 一起 做 能 成功。Zhǐyǒu dàjiā yīqǐ zuò cái néng chénggōng.Only if everyone works together can we succeed.
  • 只有 写 完 你的 作业 能 看 电视。Zhǐyǒu xiě wán nǐ de zuòyè cái néng kàn diànshì.Only if you finish your homework can you watch TV.
  • 只有 妈妈 在 我们 能 出去 玩。 Zhǐyǒu māma zài wǒmen cái néng chūqù wán.Only if Mom is here can we go out and play.
  • 只有 每天 跑步,你的 身体 会 健康。Zhǐyǒu měi tiān pǎobù, nǐ de shēntǐ cái huì jiànkāng.Only if you go running every day can you have a healthy body.
  • 只有 老板 同意 这个 建议,我们 能 做。Zhǐyǒu lǎobǎn tóngyì zhège jiànyì, wǒmen cái néng zuò.We can only do this if the boss agrees with the suggestion.
  • 只有 你 吃 过 了,你 能 说 好 不 好吃。Zhǐyǒu nǐ chī guò le, nǐ cái néng shuō hǎo bù hǎochī.You can only tell if it's good or not if you have eaten it before.
  • 只有 学习 了 拼音,你 能 更 好 地 学 汉字。Zhǐyǒu xuéxí le pīnyīn, nǐ cái néng gèng hǎo de xué hànzì.Only if you have learned pinyin can you learn Chinese characters better.

Note that for each of these examples, events have not already occurred. If they have, consider using the "only after" 才 pattern which doesn't use 只有.
