The character of cops turning up at the King's Head (5)
I believe the answer is:
spock
'the character' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'cops turning up at the king's head' is the wordplay.
'turning up' says the letters should be written backwards.
'at' means one lot of letters go next to another.
'head' says to take the initial letters.
The initial letter of 'kings' is 'k'.
'cops' reversed gives 'spoc'.
'spoc'+'k'='SPOCK'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for spock that I've seen before include "aka Leonard Nimoy" , "Star Trek character" , "In terms of childcare, a revolutionary" , "Star Trek Vulcan" .)
