After a month in Paris, man claims right to be hotel manager (6,1)
I believe the answer is:
maitre d
'be hotel manager' is the definition.
'after a month in paris man claims right' is the wordplay.
'after' says to put letters next to each other.
'a month in paris' becomes 'mai' (French for 'May').
'man' becomes 'ted' (Ted is a man's name**).
'claims' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'ted' enclosing 'r' is 'tred'.
'mai' put next to 'tred' is 'MAITRE D''.
'to' acts as a link.
(Other definitions for maitre d that I've seen before include "one waiting" , "Head waiter" , "a man to supervise dinner" , "Host" .)
