Questions & Answers about Subtraí dez.
It is the first-person singular preterite form of subtrair. In plain grammar terms, it is the I form of the simple past:
- eu subtraí = I subtracted
In European Portuguese, this tense is used for a completed action in the past.
Because Portuguese often omits the subject pronoun when the verb ending already makes the subject clear.
Here, subtraí already tells you the subject is eu. So:
- Subtraí dez. = natural and normal
- Eu subtraí dez. = also correct, but more emphatic or contrastive
This is very common in Portuguese.
