How it's used

Functions as a narrative bridge to introduce a past event or a future possibility. It is almost exclusively used in storytelling or when reflecting on life experiences rather than for specific calendar dates. When referring to a specific date in the past, use 嗰日 instead.

Examples

One day I saw him on the street.
One day you will understand.

Common phrases

Common mistake

Avoid using this to mean a specific day in the past like 'last Monday' or 'yesterday', as it implies an indefinite, non-specific point in time.
