Definition

肯定 (kěndìng)、确定 (quèdìng) 和一定 (yīdìng) 都表示对某事物的确认或确信，但侧重点和使用语境不同。肯定强调主观的承认或赞同，确定强调经过确认后没有疑问，一定强调必然性或决心。

肯定 (kěndìng), 确定 (quèdìng), and 一定 (yīdìng) all express confirmation or certainty about something, but differ in nuance and usage. 肯定 emphasizes subjective acknowledgment or approval, 确定 emphasizes being certain after verification, and 一定 emphasizes inevitability or determination.

Usage

肯定常用于表示同意、承认或肯定某人的观点、事实等，也可作副词表示当然。确定用于强调经过确认后没有怀疑，常用于指事实、计划等已明确。一定用于表示必然发生或坚定的决心，也可作形容词表示特定的。

肯定 is often used to express agreement, acknowledgment or confirmation of someone's opinion, fact, etc., and can also be an adverb meaning 'certainly'. 确定 is used to emphasize certainty after verification, often for facts, plans, etc. that are clear. 一定 is used to express inevitability or strong determination, and can also be an adjective meaning 'specific'.
