Questions & Answers about Ele ligou porque chegou cedo.
Why do both ligou and chegou end in -ou?
In the simple past tense, regular verbs that end in -ar (like ligar and chegar) take the ending -ou for the ele, ela, and você forms. So ele ligou means he called, and chegou means he arrived.
Why isn't there another ele before chegou?
In Portuguese, you can drop the subject pronoun if it is obvious who is doing the action. Since we already established the subject is ele at the beginning of the sentence, we do not need to repeat it.
I learned that verbs ending in -gar have special spelling rules in the past tense. Does that affect these words?
Why is porque written as one word here?
