So-called lion man abroad (7)
I believe the answer is:
nominal
'so-called' is the definition.
(I've seen this in another clue)
'lion man abroad' is the wordplay.
'abroad' indicates an anagram.
'lion'+'man'='lionman'
'lionman' with letters rearranged gives 'NOMINAL'.
(Other definitions for nominal that I've seen before include "Token - lion man (anag)" , "not real" , "Theoretical - token" , "Minor" , "virtually nothing" .)
