Strange dialect used in Kremlin, for example (7)
I believe the answer is:
citadel
'kremlin for example' is the definition.
(kremlin is a kind of citadel)
'strange dialect' is the wordplay.
'strange' indicates anagramming the letters.
'dialect' anagrammed gives 'CITADEL'.
'used in' is the link.
(Other definitions for citadel that I've seen before include "Bastion" , "Fortress overlooking a city" , "Fortress (in or near city)" , "Stronghold into which people could go for shelter during a battle" , "Stronghold usually within the walls" .)
