Questions & Answers about Eu entendo a questão.

Can I leave out eu and just say Entendo a questão?

Yes. In Brazilian Portuguese, subject pronouns are often omitted when the verb form already makes the subject clear.

So:

• Eu entendo a questão.
• Entendo a questão.

Both are natural and correct.

Including eu can add emphasis, contrast, or clarity. For example, Eu entendo a questão, mas ele não gives extra stress to I.

What verb is entendo, and what form is it?

Entendo is the first-person singular form of the verb entender, meaning to understand.

• você entende = you understand
• ele/ela entende = he/she understands
• nós entendemos = we understand
• vocês entendem = you all understand
• eles/elas entendem = they understand

So in this sentence, entendo tells you the subject is I.
