Fit for international selection? (7)
I believe the answer is:
capable
'fit' is the definition.
(I've seen this in another clue)
'international selection?' is the wordplay.
'international' becomes 'cap' (sportsperson who competes internationally).
'selection?' becomes 'able' (I can't explain this - if you can you should give a lot more credence to this answer).
'cap'+'able'='CAPABLE'
'for' is the link.
Can you help me to learn more?
(Other definitions for capable that I've seen before include "Of a person, competent" , "Able, competent" , "Adept" , "qualified" , "Able, proficient" .)
