Familiar name for an unfamiliar Scotsman (5)
I believe the answer is:
jimmy
'an unfamiliar scotsman' is the definition.
(way of addressing a stranger in Scottish dialect)
'familiar name' is the wordplay.
I cannot really understand how this works, but
'name' could be 'jim' and 'jim' is present in the answer.
The remaining letters 'my' 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).
'for' is the link.
Can you help me to learn more?
(Other definitions for jimmy that I've seen before include "See 16" , "Scottish term of address for a male stranger" .)
