Questions & Answers about O senhor não pode usar esta casa de banho.
Why does the translation say 'You cannot' when O senhor means 'The gentleman'?
In European Portuguese, o senhor is used as a polite, formal way to say 'you' to a man. Even though it means 'you' in this context, it takes the third-person verb form. That is why it pairs with pode (he/she/it can) rather than the informal 'you' form, podes.
Why is the second verb, usar, in its full dictionary form?
Because it follows the modal verb pode (can/may). Just like in English, when you combine a modal verb with another action, the second verb stays in its unconjugated infinitive form. So, não pode usar translates exactly to 'cannot use'.
Why is it esta instead of este for 'this'?
Is casa de banho the normal phrase for 'bathroom'?
Yes! Literally meaning 'house of bath', casa de banho is the standard, everyday phrase used in Portugal for a bathroom, restroom, or public toilet.
