An office in which little or no work gets done (8)
I believe the answer is:
sinecure
'an office' is the definition.
(I know that sinecure is a type of office)
'in which little or no work gets done' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
'work' could be 'cure' (cure is a kind of work) and 'cure' is present in the answer.
The remaining letters 'se' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for sinecure that I've seen before include "Insecure in easy job" , "Insecure in cushy job" , "Official job with little or no work" , "Undemanding job" , "position needing little effort" .)
