必要 bìyào necessary
necessary; essential; indispensable; required
怎么记住“必要”: 必 must + 要 want = necessary.
汉字
用法
- Necessary, worth doing - 有必要 / 没必要 (yǒu bìyào / méi bìyào) it's necessary / there's no need.
- Note the idiomatic pattern 有没有必要 (is it necessary), where 必要 acts as a noun 'necessity'. 没必要 is the everyday way to say 'no need to'.
- Distinguish 必要 (necessary - worth the trouble) from 必需 (bìxū, indispensable - cannot do without) and 需要 (xūyào, to need).
