A loud moral tale will make you obligingly friendly (7)
I believe the answer is:
affable
'obligingly friendly' is the definition.
'affable' can be an answer for 'friendly' (similar in meaning). I'm not sure about the 'obligingly' bit.
'a loud moral tale' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'moral tale' becomes 'fable' (I've seen this before).
'a'+'f'+'fable'='AFFABLE'
'will make you' acts as a link.
Can you help me to learn more?
(Other definitions for affable that I've seen before include "Easy to talk to" , "nice" , "Showing friendly warmth" , "Pleasantly friendly" , "Cordial, friendly" .)
