Bent author to keep repeating (8)
I believe the answer is:
penchant
'bent' is the definition.
(thesaurus)
'author to keep repeating' is the wordplay.
'author' becomes 'pen'.
'to keep repeating' becomes 'chant' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pen'+'chant'='PENCHANT'
Can you help me to learn more?
(Other definitions for penchant that I've seen before include "Partiality" , "Leaning towards or liking for" , "Inclination, bent" , "Fondness (for) - bias (towards)" , "weakness" .)
