Am given little scope (5)
I believe the answer is:
ambit
'scope' is the definition.
(synonyms)
'am given little' is the wordplay.
'given' is a charade indicator (letters next to each other).
'little' becomes 'bit' (a little is a bit).
'am'+'bit'='AMBIT'
(Other definitions for ambit that I've seen before include "Scope or confines" , "Limits" , "Scope or circuit" , "Range, scope" , "Scope, extent, or bounds of something" .)
