Bamboo thatch covering market stall (5)
I believe the answer is:
booth
'market stall' is the definition.
(individual stall in a market)
'bamboo thatch covering' is the wordplay.
'covering' indicates the answer is hidden within the clue.
'BOOTH' can be found hidden inside 'bamboo thatch'.
(Other definitions for booth that I've seen before include "Telephone housing" , "Temporary shelter" , "Army leader" , "Space for voting, phoning, etc" , "Market stall; small shop" .)
