Inclination to hypocrisy (4)
I believe the answer is:
cant
I believe this is a double definition.
'inclination' is the first definition.
(thesaurus)
'hypocrisy' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for cant that I've seen before include "Stock phrases made nonsensical by endless repetition" , "List" , "tilt" , "'Language of a group, Travellers say (4)'" , "Hypocritical talk sounds unable" .)
