For each experience has it (3)
I believe the answer is:
per
'for each' is the definition.
('per' can mean for each)
'experience has it' is the wordplay.
'has it' indicates the answer is hidden within the clue.
'PER' is hidden in the letters of 'experience'.
(Other definitions for per that I've seen before include "For each or every" , "Preposition indicating by means of" , "According to" , "Preposition meaning for each" .)
