Questions & Answers about Eu prefiro café forte de manhã.
Yes, you usually can.
Portuguese often drops subject pronouns because the verb ending already shows who the subject is. Prefiro means I prefer, so:
- Eu prefiro café forte de manhã.
- Prefiro café forte de manhã.
Both are natural.
Using Eu can add:
- emphasis: I prefer strong coffee
- contrast: Eu prefiro café, mas ela prefere chá
- clarity in some contexts
So Eu is correct, but not always necessary.
Prefiro is the 1st person singular present tense form of the verb preferir, which means to prefer.
So:
- eu prefiro = I prefer
- você prefere = you prefer
- ele/ela prefere = he/she prefers
This verb is a little irregular because the stem changes in some forms:
- preferir
- eu prefiro
- você prefere
- nós preferimos
In this sentence, prefiro tells you the speaker is talking about a general present preference.
