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 they are linked in a way 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' indicates putting letters inside.
'spar' placed around 'nne' is 'SPANNER'.
'the' is the 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" .)
