Noodles offered in party hosted by a Parisian (4)
I believe the answer is:
udon
'noodles offered' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'party hosted by a parisian' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'hosted by' means one lot of letters goes inside another.
'a parisian' becomes 'un' ('a' in French).
'do' put into 'un' is 'UDON'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for udon that I've seen is " noodle, thick".)
