否定 fǒu dìng

How 否定 is used in everyday Chinese — the speaker reads the whole sentence.

• 先肯定后否定，一正一反，就分外有力量。

  xiān kěn dìng hòu fǒu dìng yī zhèng yī fǎn jiù fèn wài yǒu lì liàng

  First acknowledge, then deny – one for and one against – and then you are in a powerful position.

• 你不能因为她所犯下的一个错误就否定她所做的一切。

  nǐ bù néng yīn wèi tā suǒ fàn xià de yī gè cuò wù jiù fǒu dìng tā suǒ zuò de yī qiè

  You shouldn't deny the validity of everything she did just because of a single mistake.
