A man to know and take to hospital (7)
I believe the answer is:
kenneth
'a man' is the definition.
'know and take to hospital' is the wordplay.
'know' becomes 'ken' (Scottish term meaning to know).
'and take' means one lot of letters go next to another.
'to hospital' becomes 'neth' (I can't explain this - if you can you should believe this answer much more).
'ken'+'neth'='KENNETH'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for kenneth that I've seen before include "- Grahame, The Wind in the Willows author" , "Boy's name" , "Man's name" , "Boy" .)
