Humour eluding Dicky (7)
I believe the answer is:
indulge
'humour' is the definition.
(I've seen this before)
'eluding dicky' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean ill or non-functioning).
'eluding' anagrammed gives 'INDULGE'.
(Other definitions for indulge that I've seen before include "pet" , "Honour" , "Treat with (undue) favour" , "Humour; spoil" , "Enjoy to excess" .)
