He joins Norm at the historic Duke's place (4)
I believe the answer is:
andy
'he' is the definition.
'norm at the historic duke's place' is the wordplay.
I cannot quite understand how this works, but
'duke' could be 'd' (abbreviation) and 'd' is located in the answer.
The remaining letters 'any' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'joins' acts as a link.
Can you help me to learn more?
(Other definitions for andy that I've seen before include "strip cartoon character" , "- Pandy, children's TV series" , "-- Capp, cartoon layabout" , "Man" , "Chap" .)
