Instrument from a laboratory upset first cosmonaut? (9)
I believe the answer is:
balalaika
'instrument' is the definition.
(type of stringed instrument)
'a laboratory upset first cosmonaut?' is the wordplay.
'laboratory' becomes 'lab' (synonyms).
'upset' says the letters should be written backwards.
'first cosmonaut?' becomes 'laika' (first dog in space).
'a'+'lab'='alab'
'alab' backwards is 'bala'.
'bala'+'laika'='BALALAIKA'
'from' is the link.
(Other definitions for balalaika that I've seen before include "Russian triangular musical instrument" , "Instrument with three strings and a triangular body" , "Foreign instrument" , "Three-stringed instrument used to play Russian folk music" , "Russian guitar-like instrument" .)
