Second goal brings delight (4)
I believe the answer is:
send
'delight' is the definition.
(I've seen this in another clue)
'second goal' is the wordplay.
'second' becomes 's' (common abbreviation).
'goal' becomes 'end' (both can mean a purpose).
's'+'end'='SEND'
'brings' acts as a link.
(Other definitions for send that I've seen before include "Transmit (message)" , "Forward" , "Despatch, remit" , "Mail" , "Transport" .)
