Queries strange man's title (7)
I believe the answer is:
esquire
'man's title' is the definition.
(I've seen this before)
'queries strange' is the wordplay.
'strange' indicates an anagram.
'queries' with letters rearranged gives 'ESQUIRE'.
(Other definitions for esquire that I've seen before include "Address of a gentleman" , "Title of courtesy for a man" , "Courtesy title for a gentleman" , "Male title on an envelope" , "Polite title" .)
