Family coming round, about to enter the cookhouse (7)
I believe the answer is:
kitchen
'cookhouse' is the definition.
(I've seen this before)
'family coming round about to enter the' is the wordplay.
'family' becomes 'kin' (synonyms).
'coming round' indicates putting letters inside.
'about to' becomes 'c' (I can't explain this - if you can you should give a lot more credence to this answer).
'enter' means one lot of letters goes inside another.
'c' placed within 'the' is 'tche'.
'kin' placed around 'tche' is 'KITCHEN'.
Can you help me to learn more?
(Other definitions for kitchen that I've seen before include "Room for preparing meals" , "Room for food" , "Proverbial place of uncomfortable heat" , "Room with proverbial heat" , "Where heat's to be stood" .)
