Would, say, ship provide a job for Ali Baba? (10)
I believe the answer is:
woodcutter
'a job for ali baba?' is the definition.
(Ali Baba is a woodcutter in folklore)
'would say ship' is the wordplay.
'say' shows a homophone (sound like).
'ship' becomes 'cutter' (type of ship).
'would' is a homophone of 'wood'.
'wood'+'cutter'='WOODCUTTER'
'provide' acts as a link.
(Other definitions for woodcutter that I've seen before include "One felling trees" , "hacking job" .)
