Name of famous auteur finally expunged? More or less (2,2)
I believe the answer is:
or so
'more or less' is the definition.
('or so' can be a synonym of 'more or less')
'name of famous auteur finally expunged?' is the wordplay.
'name of famous auteur' becomes 'orson' (Orson Welles).
'finally expunged?' means to remove the last letter (I've seen 'finally expunged' mean this).
'orson' with its last letter removed is 'OR SO'.
(Other definitions for or so that I've seen before include "roughly" , "Something like" , "Approximately" , "More or less" .)
