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 they are linked in a way I don't understand?
'tessa possibly' is the wordplay.
'possibly' is an anagram indicator.
'tessa' anagrammed gives 'SEATS'.
Can you help me to learn more?
(Other definitions for seats that I've seen before include "Chairs, stools" , "Parliamentary constituencies" .)
