First see rider’s speed then hide (10)
I believe the answer is:
canterbury
'first' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'rider's speed then hide' is the wordplay.
'rider's speed' becomes 'canter' (I can't explain this - if you can you should give a lot more credence to this answer).
'then' means one lot of letters go next to another.
'hide' becomes 'bury' (burying is a kind of hiding).
'canter'+'bury'='CANTERBURY'
'see' is the link.
Can you help me to learn more?
(Other definitions for canterbury that I've seen before include "Stand" , "Tellers of Chaucer's tales" , "where Becket fell" .)
