Man of class, maybe English, with old money and gold (8)
I believe the answer is:
educator
'man of class' is the definition.
(someone educating a class)
'english with old money and gold' is the wordplay.
'english' becomes 'e' (abbreviation).
'with' means one lot of letters go next to another.
'old money' becomes 'ducat' (historical type of coin).
'and' means one lot of letters go next to another.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'e'+'ducat'+'or'='EDUCATOR'
'maybe' acts as a link.
(Other definitions for educator that I've seen before include "Instructor" , "One who teaches others" , "Trainer, teacher" , "school worker" , "Pedagogue, teacher" .)
