Two articles about permit for gymnast, perhaps (7)
I believe the answer is:
athlete
'gymnast perhaps' is the definition.
(gymnast is a kind of athlete)
'two articles about permit' is the wordplay.
'two articles' becomes 'athe' (article meaning part of speech: the, a etc.).
'about' is an insertion indicator.
'permit' becomes 'let' ('let' can be a synonym of 'permit').
'athe' placed around 'let' is 'ATHLETE'.
'for' is the link.
(Other definitions for athlete that I've seen before include "Person trained to compete in sports" , "E.g. runner or jumper" , "eg Dean Macey" , "One trained to compete in sports" , "Competitive runner, e.g." .)
