Work outside home with fine metal sheeting (7)
I believe the answer is:
tinfoil
'metal sheeting' is the definition.
'tinfoil' can be an answer for 'metal' (I have seen 'Fine metal' mean 'tinfoil' so perhaps 'metal' could also mean 'tinfoil'). I am not certain of the 'sheeting' bit.
'work outside home with fine' is the wordplay.
'work' becomes 'toil' (toil is a kind of work).
'outside' is an insertion indicator (some letters go outside others).
'home' becomes 'in' (to be in is to be (at) home).
'with' is a charade indicator (letters next to each other).
'fine' becomes 'f' (abbreviation in pencil classifications).
'in'+'f'='inf'
'toil' enclosing 'inf' is 'TINFOIL'.
Can you help me to learn more?
(Other definitions for tinfoil that I've seen before include "Wrapping around food" , "Food wrapper" , "Thin metal sheet for wrapping food etc" , "This coverage" , "up to wrapping up dope" .)
