Hard to cry over American (7)
I believe the answer is:
callous
'hard' is the definition.
('callous' can be similar in meaning to 'hard')
'cry over american' is the wordplay.
'cry' becomes 'call' ('call' can be a synonym of 'cry'**).
'over' becomes 'o' (cricket abbreviation).
'american' becomes 'us'.
'call'+'o'+'us'='CALLOUS'
'to' acts as a link.
(Other definitions for callous that I've seen before include "Insensitive, cruel" , "Heartless" , "Not feeling" , "Cruel or unsympathetic" , "Cruel and unfeeling" .)
