Nearly everything in pavilion is bent (6)
I believe the answer is:
talent
'is bent' is the definition.
(I've seen this in another clue)
'nearly everything in pavilion' is the wordplay.
'nearly' means to remove the last letter.
'everything' becomes 'all' (all things).
'in' indicates putting letters inside.
'pavilion' becomes 'tent' (I've seen this in another clue).
'all' with its final letter taken off is 'al'.
'al' placed into 'tent' is 'TALENT'.
(Other definitions for talent that I've seen before include "Natural aptitude of an old coin" , "Natural ability or quality" , "ancient currency" , "Gift - aptitude" , "Natural endowment" .)
