Inclined to be responsible (6)
I believe the answer is:
liable
I believe this is a double definition.
'inclined' is the first definition.
(I've seen this before)
'responsible' is the second definition.
(similar in meaning)
'to be' acts as a link.
(Other definitions for liable that I've seen before include "Subject to an obligation" , "Apt to" , "To blame" , "legally obliged, held responsible" , "Responsible at law" .)
