Hence in another goal (4)
I believe the answer is:
ergo
'hence' is the definition.
(I've seen this before)
'in another goal' is the wordplay.
'in' indicates a hidden word.
'ERGO' is hidden within 'another goal'.
(Other definitions for ergo that I've seen before include "Thus" , "Therefore - what a goer" , "'Cogito, ---- sum'" , "Therefore (Latin)" , "so philosopher wrote in Latin" .)
