View the empty goal (5)
I believe the answer is:
tenet
'view' is the definition.
(thesaurus)
'the empty goal' is the wordplay.
'empty' says to hollow out the word (remove centre letters).
'goal' becomes 'net' (net is a kind of goal).
'the' with its middle taken out is 'te'.
'te'+'net'='TENET'
(Other definitions for tenet that I've seen before include "Doctrine held to be true" , "you may believe in it" , "Doctrine; principle held" , "Rule" , "A palindromic doctrine or belief" .)
