What may show twenty with chap bagging a run? (10)
I believe the answer is:
'what may' is the definition.
I can't judge whether this defines the answer.
'twenty with chap bagging a run?' is the wordplay.
'twenty' becomes 'score' ('score' can be a synonym of 'twenty').
'with' is a charade indicator (letters next to each other).
'chap' becomes 'bo'.
'bagging a run?' becomes 'ard' (I can't explain this - if you can you should believe this answer much more).
'score'+'bo'+'ard'='SCOREBOARD'
'show' is the link.
Can you help me to learn more?
(Other definitions for scoreboard that I've seen before include "It shows state of game" , "Indicator of the state of play" , "Where match results are displayed" , "On which points are tallied" , "It should feature up-to-date numbers" .)
