Stall in market's beginning to wind up (6)
I believe the answer is:
manger
'stall' is the definition.
(thesaurus)
'market's beginning to wind up' is the wordplay.
'beginning to' indicates taking the first letters.
'wind up' becomes 'anger' (wind up can mean to annoy or anger).
The initial letter of 'markets' is 'm'.
'm'+'anger'='MANGER'
'in' is the link.
(Other definitions for manger that I've seen before include "Trough for horse or cattle food" , "In which Jesus was born" , "Container from which horses feed" , "Trough for animal feed" , "laying heavenly baby here?" .)
