Implement often found in the works (7)
I believe the answer is:
spanner
'works' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'implement often found in' is the wordplay.
'implement' becomes 'spar' (spar is a kind of implement).
'often found' becomes 'nne' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
'spar' enclosing 'nne' is 'SPANNER'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for spanner that I've seen before include "Type of wrench" , "that might cause difficulty in the works" , "Hand tool to grip and turn" , "Hand tool for nuts" , "murder weapon" .)
