Bag carried in is accessed (3)
I believe the answer is:
sac
'bag' is the definition.
(a small bag)
'carried in is accessed' is the wordplay.
'carried' indicates a hidden word.
'SAC' is hidden in the letters of 'in is accessed'.
(Other definitions for sac that I've seen before include "Bladder" , "Pouch or bag-like structure" , "Bodily pouch" , "Bag-like part of the body" , "Traditional entitlement to hold court" .)
