How it's used

The particle 定 here functions as a resultative complement indicating that an action is completed in preparation for a future event. It implies foresight and planning, ensuring that something is ready before it is actually needed. While it is common in gambling to mean locking in a bet, in everyday life it is simply the go-to way to express buying something ahead of time.

Examples

I've already bought the tickets, I'll go watch the movie on time tomorrow.
Have you bought the groceries in advance yet?

Common phrases

place your bets (no more bets)
buy things in advance

Common mistake

Do not confuse this with the verb 定, which can mean to decide or to fix. When used as a complement like in 買定, it specifically emphasizes the preparatory nature of the action rather than just the act of buying itself.
