Foot in door with pained expression, might one be slated? (4)
I believe the answer is:
roof
'one be slated?' is the definition.
I can't tell whether this definition defines the answer.
'foot in door with pained expression' is the wordplay.
'foot in' indicates one should take the final letters (bottom/final letter of - in down clue).
'with pained expression' becomes 'oof' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The last letter of 'door' is 'r'.
'r'+'oof'='ROOF'
'might' acts as a link.
Can you help me to learn more?
(Other definitions for roof that I've seen before include "Part of mouth" , "Eg, mansard, gambrel" , "Top outside covering" , "Upper limit; house top" , "Topping structure" .)
