Insensitive Opposition leader with American chasing visit (7)
I believe the answer is:
callous
'insensitive' is the definition.
('callous' can be similar in meaning to 'insensitive')
'opposition leader with american chasing visit' is the wordplay.
'leader' suggests taking the first letters.
'with american' becomes 'us' (I am not sure about the 'with' bit.**).
'chasing' is a charade indicator (letters next to each other).
'visit' becomes 'call' ('call' can be a synonym of 'visit').
The first letter of 'opposition' is 'o'.
'o'+'us'='ous'
'ous' put after 'call' is 'CALLOUS'.
Can you help me to learn more?
(Other definitions for callous that I've seen before include "Hard-hearted" , "Cruel or unsympathetic" , "Heartless" , "Emotionally hardened" , "Not feeling" .)
