Somehow merits a title (6)
I believe the answer is:
mister
'a title' is the definition.
(I know that Mister is a type of title)
'somehow merits' is the wordplay.
'somehow' indicates anagramming the letters.
'merits' anagrammed gives 'MISTER'.
(Other definitions for mister that I've seen before include "Male form of address" , "Merits of form of address to man" , "Set rim (anag.)" , "Bloke" , "Form of address to a man, used without his name" .)
