He could get riled if made to work (5)
I believe the answer is:
idler
'he could' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'riled if made to work' is the wordplay.
'riled' anagrams to 'IDLER'.
However, I'm not clear how this is indicated.
'get' acts as a link.
Can you help me to learn more?
(Other definitions for idler that I've seen before include "One avoiding work" , "Slow-cooked dish" , "Unpowered guide pulley" , "Good-for-nothing" , "Lazy type" .)
