Perhaps like Bengali's reduced charge (5)
I believe the answer is:
indic
'perhaps like bengali's' is the definition.
(relating to an Indian language eg Bengali)
'reduced charge' is the wordplay.
'reduced' means to remove the last letter.
'charge' becomes 'indict' (indicting is a kind of charging).
'indict' with its last letter removed is 'INDIC'.
(Other definitions for indic that I've seen before include "Language" , "Like some tongues" , "Group of languages including Sanskrit" .)
