Scottish name in a new form (3)
I believe the answer is:
ian
'scottish name' is the definition.
(I've seen this in another clue)
'in a new form' is the wordplay.
'new form' is an anagram indicator (I've seen 'new form of' mean this).
'in'+'a'='ina'
'ina' with letters rearranged gives 'IAN'.
(Other definitions for ian that I've seen before include "The familiar Mr Paisley" , "- McEwan, Eng. writer" , "Sir - McKellen, actor" , "Albert Beale's first name in EastEnders" , "- Fleming (James Bond)" .)
