a por

1. (Spain) In search of; to go and get; to fetch. This phrase often implies movement towards a goal or object with the intention of acquiring it.

   Voy a por el pan.

   (I'm going to get the bread / I'm going for the bread.)

   Corre a por la pelota.

   (Run to get the ball / Run for the ball.)

   Han ido a por agua.

   (They have gone to fetch water / They have gone for water.)

   ¡A por ellos!

   (Go get 'em! / Go after them!)

This construction is primarily used in Spain. In Latin America, the preposition por alone (or other verbs/phrases) is typically used to convey a similar meaning. The use of "a por" can emphasize the "going to get" aspect more strongly than just "por." It also helps to avoid ambiguity with other meanings of "por."
