Charm Frenchman at meeting (6)
I believe the answer is:
mascot
'charm' is the definition.
(synonyms)
'frenchman at meeting' is the wordplay.
'frenchman' becomes 'm' (abbreviation for Monsieur - like 'Mr').
'at' means one lot of letters go next to another.
'meeting' becomes 'ascot' (horse racing meeting).
'm'+'ascot'='MASCOT'
(Other definitions for mascot that I've seen before include "Charm - talisman" , "One is lucky" , "Symbolic figure, of a team perhaps" , "Does it get you first place" , "Team's good luck bringer" .)
