Winter boot created by society duchess (5)
I believe the answer is:
skate
'winter boot' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'by society duchess' is the wordplay.
'by' is a charade indicator (letters next to each other).
'society' becomes 's' (common abbreviation in names of organisations).
'duchess' becomes 'kate' (Catherine, Duchess of Cambridge).
's' next to 'kate' is 'SKATE'.
'created' acts as a link.
Can you help me to learn more?
(Other definitions for skate that I've seen before include "A ray; slide smoothly" , "Large, edible rays" , "Recite Keats badly to the fish" , "Fish of ray family" , "Glide on ice; ray" .)
