Suitably prepares to show a girl points (6)
I believe the answer is:
adapts
'suitably prepares to' is the definition.
I can't judge whether this defines the answer.
'a girl points' is the wordplay.
'a girl' becomes 'Ada' (girl's name).
'points' becomes 'pts' (I can't explain this - if you can you should believe this answer much more).
'ada'+'pts'='ADAPTS'
'show' is the link.
Can you help me to learn more?
(Other definitions for adapts that I've seen before include "Fits" , "Modifies or changes for another use" , "Change to fit new circumstances" , "Alters to suit another purpose" , "Alters to fit" .)
