Questions & Answers about Eu comuniquei o sinistro.

Why is eu included? Can I leave it out?

Yes, you usually can leave it out.

Portuguese often drops subject pronouns when the verb already makes the subject clear. Since comuniquei clearly means I communicated / I reported, Eu comuniquei o sinistro and Comuniquei o sinistro both work.

Using eu adds emphasis or clarity, for example:

• to contrast with someone else
• to sound more explicit
• to avoid ambiguity in conversation

So in many situations, Comuniquei o sinistro would sound perfectly natural.

What tense is comuniquei?

Comuniquei is the 1st person singular of the preterite of comunicar.

That means it refers to a completed action in the past:

• eu comuniquei = I communicated / I reported / I notified

This is different from:

• eu comunicava = I used to communicate / I was communicating
• eu comunico = I communicate / I am communicating
• eu tenho comunicado = I have been communicating / I have communicated

So here the speaker is talking about one finished past action.
