Stallions encircle ten workrooms (7)
I believe the answer is:
studios
'workrooms' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'stallions encircle ten' is the wordplay.
I cannot quite understand how this works, but
'ten' could be 'io' (IO resembles 10) and 'io' is present in the answer.
'stallions' could be 'studs' (stud is a kind of stallion) and 'studs' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for studios that I've seen before include "Artists' workrooms" , "Ateliers" , "makers of movies" , "Places where artists or TV performers work" .)
