Compliant, having the last word? Clever (8)
I believe the answer is:
amenable
'compliant' is the definition.
(similar in meaning)
'the last word? clever' is the wordplay.
'the last word?' becomes 'amen' (last word in a prayer).
'clever' becomes 'able' (able can mean skilled or talented).
'amen'+'able'='AMENABLE'
'having' is the link.
(Other definitions for amenable that I've seen before include "Easily persuaded or controlled" , "Prepared to fall in with others' plans" , "Willing to yield or be influenced" , "Easily influenced" , "Open to suggestions" .)
