Try tango, love (5)
I believe the answer is:
heart
'love' is the definition.
(heart is a kind of love)
'try tango' is the wordplay.
'try' becomes 'hear' (as in to try someone in court or hear their case**).
'tango' becomes 't' (phonetic alphabet: alpha, bravo, charlie etc.).
'hear'+'t'='HEART'
(Other definitions for heart that I've seen before include "Muscular organ - compassion" , "Kernel" , "one needs to beat" , "Muscular organ for blood circulation" , "Playing card - pity" .)
