Historic works surrounding small office of medical specialist (11)
I believe the answer is:
chiropodist
'medical specialist' is the definition.
(chiropodist is a kind of medical specialist)
'historic works surrounding small office of' is the wordplay.
I cannot really understand how this works, but
'works' could be 'is' ('be' can be a synonym of 'work') and 'is' is found in the answer.
'of' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chiropodist that I've seen before include "Specialist in the treatment of feet" , "Treater of feet" , "corn cutter" , "Foot specialist" , "Foot doctor" .)
