Hence in another gondola (4)
I believe the answer is:
ergo
'hence' is the definition.
(I've seen this in another clue)
'in another gondola' is the wordplay.
'in' says the answer is hidden in the clue.
'ERGO' can be found hidden inside 'another gondola'.
(Other definitions for ergo that I've seen before include "for this reason" , "Hence" , "Thus" , "so philosopher wrote in Latin" , "as a consequence" .)
