reception room

'for entertaining' is the definition.
I can't tell whether this defines the answer.

'welcome space' is the wordplay.
'welcome' becomes 'reception' (I've seen this before).
'space' becomes 'room' (enough space or room to do something).
'reception'+'room'='RECEPTION ROOM'

'used' is the link.

Can you help me to learn more?

(Other definitions for reception room that I've seen before include "Entertaining space" , "Public area" .)

I've seen this clue in The Daily Express.
