Various items: a lot seen around one's place of confinement (10)
I believe the answer is:
miscellany
'various items' is the definition.
(miscellaneous items)
'a lot seen around one's place of confinement' is the wordplay.
'a lot' becomes 'many' (many means a lot).
'seen around' is an insertion indicator.
'one's' becomes 'i's' (Roman numeral).
'place of confinement' becomes 'cell' (I've seen this before).
'is'+'cell'='iscell'
'many' going around 'iscell' is 'MISCELLANY'.
(Other definitions for miscellany that I've seen before include "potpourri" , "motley group?" , "Hotch-potch" , "Mixture" , "anthology" .)
