Comes to a halt in the auditorium (6)
I believe the answer is:
stalls
This clue could be a double definition.
'comes to a halt' is the first definition.
(stalling is a kind of coming to a halt)
'auditorium' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for stalls that I've seen before include "Evasive moves" , "Posh seats in the theatre" , "pews" , "Cuts out in parterre?" , "Deliberately delays" .)
