A little half-pint hero undaunted on central stage (2,3,5)
I believe the answer is:
in the round
'central stage' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'a little half-pint hero undaunted' is the wordplay.
'a little' indicates the answer is hidden within the clue (a little bit of the clue).
'IN THE ROUND' is hidden within 'half pint hero undaunted'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for in the round that I've seen before include "Theatre where the stage is sited among the audience" , "All things considered" .)
