For each experience has it (3)
I believe the answer is:
per
'for each' is the definition.
(per person)
'experience has it' is the wordplay.
'has it' indicates a hidden word.
'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" .)
