"She finishes writing the letter."

Translation: Ela termina de escrever a carta.

[malvinalynn]

It would have been nice if the hint mentioned that we needed to add "de" after the verb terminar

[MariaSilfverberg]

Is it Always termina +de ?

[Paulenrique]

Yes. Terminar + de + verb.

[andrea_duque]

Shouldn't acaba be accepted????

[chicca63]

Ela acaBa, of course

[Paulenrique]

It is also acceptable, but most of time we use acabar+de + infinitive meaning have+just+participle
