Small travelling bag (6)
I believe the answer is:
valise
'small travelling bag' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for valise that I've seen before include "Travel bag" , "A small suitcase for Leavis" , "Small overnight bag" , "Elvis A? (anag)" , "Small travelling bag or suitcase" .)
