The short answer
Começar works in many everyday situations: beginning a class, starting work, opening a conversation, or starting to learn a skill. It can take a noun or an infinitive phrase, as in começar a estudar (start studying).
Use começar for a person, activity, or event getting underway
In casual Brazilian speech, começar is a flexible default when you are simply saying that an activity is beginning.
A aula começa às nove.
The class starts at nine.
Comecei a estudar português no ano passado.
I started studying Portuguese last year.
Vamos começar pelo primeiro exercício.
Let’s start with the first exercise.
Use iniciar for a process or a more formal instruction
Iniciar often frames the start of a process, procedure, system, or formal activity. You may see it in instructions, work settings, or digital interfaces. In many contexts, começar is also possible, but iniciar gives the sentence a more structured tone.
Both verbs are regular -ar verbs in these examples. Conjugate the verb for the subject and keep the following noun or infinitive phrase clear.
