Was curious about the work and foolishly nosed about (7)
I believe the answer is:
snooped
'nosed about' is the definition.
'snooped' can be an answer for 'nosed' (I've seen this in another clue). I am unsure of the 'about' bit.
'was curious about the work and foolishly' is the wordplay.
I cannot quite understand how this works, but
'work' could be 'op' (short for opus) and 'op' is located in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for snooped that I've seen is " Pried".)
