Tessa possibly stalls (5)
I believe the answer is:
seats
'stalls' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'tessa possibly' is the wordplay.
'possibly' indicates an anagram.
'tessa' with letters rearranged gives 'SEATS'.
Can you help me to learn more?
(Other definitions for seats that I've seen before include "Chairs, stools" , "Parliamentary constituencies" .)
