How it is used
- An adverb asserting something is bound to happen - 努力必定有回报 (nǔlì bìdìng yǒu huíbào) effort is sure to be rewarded.
- Expresses the speaker's confident certainty/inference, like 一定 but firmer and more formal; not a command.
- Contrast 必须 (bìxū, 'must' = obligation); 必定 = 'surely will,' 必须 = 'have to.'
