How to use it

'định' is often used to express 'I intend to' or 'I was planning to'. Both 'định' and 'sẽ' refer to the future, but 'định' is more subjective, indicating intention or plan; 'sẽ' is more like a general future or promise.

  • Commonly used for personal plans.
  • Can be used in questions to ask about plans.
  • Does not imply the plan is definitely arranged or finalized.

Compared with English

Compared with English

In English, 'will' is broad, but Vietnamese distinguishes 'will' as 'sẽ', 'intend to' as 'định', and 'about to' as 'sắp'.
