Puritan to turn on leader (9)
I believe the answer is:
roundhead
'puritan' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'turn on leader' is the wordplay.
'turn on' becomes 'round' (synonyms. I am not sure about the 'on' bit.).
'leader' becomes 'head' (head is a kind of leader).
'round'+'head'='ROUNDHEAD'
'to' is the link.
Can you help me to learn more?
(Other definitions for roundhead that I've seen before include "antimonarchist" , "Supporter of Parliament during the English Civil Wars" , "Old soldier" , "Cavalier's foe" , "Parliamentarian (hist.)" .)
