Questions & Answers about Preciso transmitir a declaração do Imposto de Renda hoje.

Why is eu missing at the beginning?

Because Portuguese often drops the subject pronoun when the verb form already shows who the subject is.

• Preciso is the I form of precisar
• So Preciso transmitir... already means I need to submit/file...

You can say Eu preciso transmitir... if you want emphasis, contrast, or extra clarity, but leaving out eu is very normal.

What does preciso mean here?

Here, preciso is the verb precisar in the I form, so it means I need.

This can confuse English speakers because preciso can also be an adjective meaning precise or exact in other contexts.

In this sentence, it is clearly a verb because it is followed by another verb, transmitir:

• Preciso transmitir = I need to submit/transmit

Why is it preciso transmitir and not preciso de transmitir?

Because Portuguese uses two common patterns with precisar:

• precisar + infinitive = to need to do something
• precisar de + noun = to need something

So:

• Preciso transmitir a declaração. = I need to submit the return.
• Preciso de ajuda. = I need help.

That is why there is no de before transmitir.
