Questions & Answers about Dei um pequeno passo.
Dei is the first-person singular form of the verb dar in the simple past (also called the preterite).
- dar = to give
- dei = I gave
In the expression dar um passo, Portuguese uses dar where English usually says take a step.
This verb is irregular, so dei does not look very much like dar.
Portuguese often leaves out subject pronouns when the verb form already makes the subject clear.
So:
- Dei um pequeno passo.
- Eu dei um pequeno passo.
Both are correct. The version without eu is very natural and common.
Because dei can only mean I gave, the subject is already obvious.
Dei is in the preterite, which is used for a completed action in the past.
So Dei um pequeno passo presents the action as one finished event: I took/made one small step.
Compare:
- Dei um pequeno passo. = completed action
- Dava pequenos passos. = I used to take small steps / I was taking small steps
So here the speaker is referring to one specific step or one completed act.
