Noodles offered in party hosted by a Parisian (4)
I believe the answer is:
udon
'noodles offered' is the definition.
I don't know anything about this answer so I can't 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' is an insertion indicator.
'a parisian' becomes 'un' ('a' in French).
'do' inserted into 'un' is 'UDON'.
'in' is the link.
Can you help me to learn more?
(Another definition for udon that I've seen is " noodle, thick".)
