A priority is the value of a move that decides when it is used in a turn.
Only when two moves have the same priority value will the speed of the users be used to decide the order. Even Trick Room cannot affect the order of the moves if it has been decided by their priority.
Priority ranges from +5 to -7. Usually, positive priority allows a move to be used first, and negative priority forces a move to be used last.

- The items Quick Claw, Custap Berry, Lagging Tail, Full Incense and the ability Stall can change the order of moves, but they are unable to affect an order determined by priority.
- If the move Pursuit targets a Pokémon switching out, its priority changes from 0 to even surpasses +5, for switching Pokémon usually goes before any move executing.
