Witches struggle in city (8)
I believe the answer is:
coventry
'city' is the definition.
(I know that city can be written as Coventry)
'witches struggle' is the wordplay.
'witches' becomes 'coven' (I've seen this in other clues).
'struggle' becomes 'try' (I can't explain this - if you can you should believe this answer much more).
'coven'+'try'='COVENTRY'
'in' is the link.
Can you help me to learn more?
(Other definitions for coventry that I've seen before include "Send to this city to ostracise" , "English city" , "City devastated in World War II" , "Has a 5 across designed by Basil Spence" , "Place" .)
