Falling behind in providing winter insulation? (7)
I believe the answer is:
lagging
'insulation?' is the definition.
(I know that lagging is a type of insulant)
'falling behind in providing winter' is the wordplay.
'falling behind' becomes 'lag' (I've seen this in another clue).
'in providing winter' becomes 'ging' (I can't justify this - if you can you should believe this answer much more).
'lag'+'ging'='LAGGING'
Can you help me to learn more?
(Other definitions for lagging that I've seen before include "Insulation -- failing to keep up" , "Insulating material" , "It's used to wrap around boilers, say, to prevent heat-loss" , "job in the attic?" , "Wrapping used to prevent loss of heat" .)
