Questions & Answers about Esta sala serve para estudar em silêncio.
Why is it esta sala and not este sala?
Because sala is a feminine singular noun, so the demonstrative has to match it:
- esta sala = this room
- este quarto = this bedroom/room
So esta agrees with sala in gender and number.
Why is it esta and not essa?
In European Portuguese, the demonstratives usually work like this:
- esta = this, near the speaker
- essa = that, near the listener or already mentioned
- aquela = that over there, farther away
So esta sala means this room. In real conversation, native speakers do not always follow the distance distinction perfectly, but this is the basic system learners should know.
What does sala mean here exactly?
Sala is a general word for a room or hall. Depending on context, it can mean things like:
- living room
- classroom
- waiting room
- study room
In this sentence, it just means a room intended for studying. English often needs a more specific word, but Portuguese can stay broader.
