'not having much enthusiasm only' is the definition.
I can't judge whether this defines the answer.

'partly listen to edward' is the wordplay.
'partly' becomes 'half' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'listen to' becomes 'hear' (to hear something is to listen to it).
'edward' becomes 'ted'.
'half'+'hear'+'ted'='HALFHEARTED'
