Questions & Answers about Eu preciso confirmar o endereço na internet antes de sair.
Why does Portuguese use eu preciso here—could I leave out eu?
Yes, you can often omit the subject pronoun in Portuguese because the verb ending already shows who the subject is.
- (Eu) preciso confirmar o endereço... both are natural.
Including eu can add a bit of emphasis or clarity (for example, in contrast with someone else).
What’s the difference between eu preciso and eu tenho que in Brazilian Portuguese?
Both can mean I need to / I have to, but there’s a nuance:
- Eu preciso + infinitive often sounds like a personal need/requirement: I need to confirm...
- Eu tenho que + infinitive can sound more like obligation/necessity, sometimes stronger: I have to confirm...
In everyday Brazilian Portuguese, both are common and often interchangeable.
Why is it confirmar and not a conjugated verb like confirmo?
Because precisar is followed by an infinitive to express need to do something:
- Eu preciso confirmar... = I need to confirm...
If you used confirmo, it would become two separate ideas (and would usually need restructuring), e.g. Eu confirmo... = I confirm...
Does o endereço mean a street address or an internet/website address?
Endereço can mean either, depending on context:
- physical address: endereço (de casa / do lugar)
- web address/URL: often clarified as endereço do site, endereço eletrônico, or simply o link
In this sentence, na internet strongly suggests you mean checking the address online (likely the location’s address, though it could also be a URL in some contexts).
Why is there an article o before endereço? Can I say confirmar endereço?
Brazilian Portuguese commonly uses articles before nouns in general statements:
- confirmar o endereço is the most natural in most contexts.
You can say confirmar endereço, but it sounds more like a sign/instruction style or more generic/less specific. In normal conversation, o endereço is preferred.
What does na internet literally mean, and why is it na?
Na is a contraction of em + a:
- em = in/on
- a = the (feminine singular)
So na internet literally = on the internet / online.
Portuguese treats internet as feminine here: a internet → na internet.
Could I also say pela internet or no Google instead?
Yes, but the meaning shifts slightly:
- na internet = on the internet / online (location/medium)
- pela internet = via the internet (method/channel)
- no Google = on Google (more specific platform)
Examples: - confirmar o endereço na internet (online in general)
- confirmar o endereço no Google (specifically using Google)
Why is it antes de sair and not antes de eu sair?
Both exist:
- antes de sair = before leaving (general, subject understood as the same person)
- antes de eu sair = before I leave (explicit subject, can add emphasis/clarity)
If the subject could be someone else, Portuguese often clarifies: antes de ele/ela sair.
Is sair here “to leave” as in leaving home, or leaving a place/event?
Sair means to leave / to go out, and context decides:
- leaving home to go somewhere: antes de sair (de casa)
- leaving a place/event: antes de sair (do trabalho / da festa)
If you want to be explicit, you can add the place: antes de sair de casa.
How would I make this sentence more natural in casual Brazilian Portuguese?
Your sentence is already natural. A few common casual variations:
- Preciso confirmar o endereço na internet antes de sair. (drops eu)
- Preciso checar o endereço online antes de sair. (checar and online are very common)
- Tenho que ver o endereço na internet antes de sair. (more “I have to”)
