Cleaner getting sick by raid carried out in recreation area (8,4)
I believe the answer is:
billiard room
'area' is the definition.
(billiard room is a kind of area)
'cleaner getting sick by raid carried out in recreation' is the wordplay.
I cannot quite understand how this works, but
'sick' could be 'ill' (similar in meaning) and 'ill' is found in the answer.
an anagram of 'raid' is 'iard' which is within the answer.
'cleaner' could be 'broom' (I've seen this before) and 'broom' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for billiard room that I've seen is " Where one takes one's cue?".)
