Pay for each experience at the start (3)
I believe the answer is:
fee
'pay' is the definition.
(thesaurus)
'for each experience at the start' is the wordplay.
'at the start' suggests taking the first letters.
The first letters of 'for each experience' is 'FEE'.
(Other definitions for fee that I've seen before include "Sum payable to professional person for services" , "price" , "Payment to a professional for services" , "Cost" , "Amount paid for job" .)
