Instrument brought back from Bratislava (5)
I believe the answer is:
sitar
'instrument' is the definition.
(sitar is a kind of instrument)
'brought back from bratislava' is the wordplay.
'brought back' is a reversal indicator.
'from' indicates a hidden word.
'ratis' is hidden within 'bratislava'.
'ratis' backwards is 'SITAR'.
(Other definitions for sitar that I've seen before include "Large Indian lute" , "Long necked and often plucked" , "Guitar-like instrument" , "Long-necked musical instrument of India" , "Hindu stringed instrument" .)
