Punished when half the team gad about (5)
I believe the answer is:
gated
'punished' is the definition.
Although both the answer and definition are past participle verbs, I don't see how one could define the other.
'half the team gad about' is the wordplay.
'half the' means to take half the letters.
'about' is an insertion indicator.
'team' cut in half is 'te'.
'te' going into 'gad' is 'GATED'.
'when' is the link.
Can you help me to learn more?
(Other definitions for gated that I've seen before include "kept in school" , "Forbidden to leave college" , "Confined to college" , "temporarily confined" , "Confined to school" .)
