Dressing room vs. Dress room

It's a dressing room. It's not uncommon for what we call rooms to tell us what goes on in them - living room, sitting room, dining room.

I cannot understand this sentence: "It's not uncommon for what we call rooms to tell us what goes on in them". Please clarify the sentence for me. Thanks.

It is quite common for the names of rooms to give us an idea of what happens in those rooms.

Good!

I am interested to know the reason for the name drawing room?

Thanks,

I believe the original term many years ago was 'withdrawing room'.

The room that people would withdraw to, eg when they finished eating in the dining room.

Modern houses have no drawing room.

Thanks, Clive.

Where I live, the term drawing room is very, very common.
