One putting out second fire in room (5)
I believe the answer is:
ingle
'fire in room' is the definition.
'ingle' can be an answer for 'fire' (ingle means a fireplace). I am unsure of the 'in room' bit.
'one putting out second' is the wordplay.
'one' becomes 'single' (synonyms).
'putting out' is a deletion indicator.
'second' becomes 's' (common abbreviation).
'single' with 's' taken away is 'INGLE'.
Can you help me to learn more?
(Other definitions for ingle that I've seen before include "Sort of nook" , "Dizziness from imbalance" , "Fireplace blaze (Scot.)" , "Catamite" , "Warm corner" .)
