Was inclined to have told lies about a saint (6)
I believe the answer is:
listed
'was inclined to' is the definition.
I can't judge whether this definition defines the answer.
'told lies about a saint' is the wordplay.
'told lies' becomes 'lied' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' is an insertion indicator.
'a saint' becomes 'st' (abbreviation).
'lied' going around 'st' is 'LISTED'.
'have' acts as a link.
Can you help me to learn more?
(Other definitions for listed that I've seen before include "Quoted on the London Stock Exchange" , "Silted up and leaned over" , "Once liked" , "Entered names of idlest sort" , "put something on ebay?" .)
