Idleness seen at work (8)
I believe the answer is:
inaction
'idleness' is the definition.
(thesaurus)
'at work' is the wordplay.
'at' becomes 'in' (synonymous in some cases - eg at school, in school).
'work' becomes 'action' (I can't explain this - if you can you should believe this answer much more).
'in'+'action'='INACTION'
'seen' is the link.
Can you help me to learn more?
(Other definitions for inaction that I've seen before include "Failure to do anything" , "Idleness - fighting" , "This is not working" , "Immobility" , "Lack of movement or endeavour" .)
