Token or note oilman tossed (7)
I believe the answer is:
nominal
'token' is the definition.
(I know that token can be written as nominal)
'note oilman tossed' is the wordplay.
'note' becomes 'n' (abbreviation).
'tossed' is an anagram indicator.
'oilman' is an anagram of 'ominal'.
'n'+'ominal'='NOMINAL'
'or' acts as a link.
(Other definitions for nominal that I've seen before include "Trivial" , "In name only or of token value (7)" , "Existing in name only" , "In name only or token payment" , "Token - lion man (anag)" .)
