Damaged sword in Berkshire town (7)
I believe the answer is:
windsor
'berkshire town' is the definition.
'windsor' can be an answer for 'town' (I've seen this before). I'm not sure about the 'berkshire' bit.
'damaged sword in' is the wordplay.
'damaged' is an anagram indicator.
'sword'+'in'='swordin'
'swordin' is an anagram of 'WINDSOR'.
Can you help me to learn more?
(Other definitions for windsor that I've seen before include "Family name replacing Saxe-Coburg-Gotha in 1917" , "Thames town" , "Royal castle; a tie knot" , "British royal house" , "Type of soap" .)
