< Portuguese Grammar

começar + a

You always need to place an “a” right after the verb COMEÇAR when another verb follows. It’s a rule. COMEÇAR without a following verb doesn’t need the “a”.

Eu vou começar a correr. (I'm going to start to run.)

Estou começando a aprender. (I'm starting to learn.)

Quando você vai começar a trabalhar (When are you going to start work?)
