Division of an English county is a square (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
hundred
'division of an english county' is the definition.
'hundred' can be an answer for 'county' (thesaurus). I'm not sure about the 'division of an english' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hundred that I've seen before include "See 19" , "so many others" , "Subdivision of shire; ton" , "cricketing achievement" , "Old subdivision of a shire or county" .)
