Questions & Answers about Eu prefiro a sopa sem pimenta.
You can absolutely drop eu.
In Brazilian Portuguese, subject pronouns are often omitted when the verb already makes the subject clear. So:
- Eu prefiro a sopa sem pimenta.
- Prefiro a sopa sem pimenta.
Both are natural.
Including eu can add:
- emphasis: I prefer the soup without pepper.
- contrast: I prefer it, but someone else may not.
Because prefiro is the conjugated form of the verb preferir for I in the present tense.
- preferir = to prefer
- eu prefiro = I prefer
A few present-tense forms are:
- eu prefiro
- você prefere
- ele/ela prefere
- nós preferimos
- vocês preferem
- eles/elas preferem
So prefiro matches the subject eu.
