Present Continuous

To say "I am walking" in Portuguese, you need two things: the right form of estar, and the verb in its gerúndio form. The gerúndio is built by dropping the infinitive ending and adding -ando (-ar verbs), -endo (-er), or -indo (-ir).

Infinitive	Gerúndio	Example
andar	andando	Eu estou andando. — I am walking.
comer	comendo	Você está comendo. — You are eating.
abrir	abrindo	Ele está abrindo a porta. — He is opening the door.

Notice it's estar that conjugates with the subject, not the main verb — the main verb just sits in its gerúndio form.

Drill: estar (you'll need this for every sentence)
