Dangerous to change sides in supper to make room (7)
I believe the answer is:
parlour
'room' is the definition.
(parlour is a kind of room)
'dangerous to change sides in supper' is the wordplay.
I cannot quite see how this works, but
'sides' could be 'rl' (I've seen this in other clues) and 'rl' is located in the answer.
This may be the basis of clue (or it may be nonsense).
'to make' is the link.
Can you help me to learn more?
(Other definitions for parlour that I've seen before include "Shop etc, formerly front room" , "Confident, daring" , "Beauty room?" , "Living room - where farmers milk cows?" , "Room in public house" .)
