Some man near former monarch (4)
I believe the answer is:
anne
'monarch' is the definition.
(Queen Anne, 18th-century queen)
'some man near former' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ANNE' is hidden within 'man near former'.
(Other definitions for anne that I've seen before include "--- Elliot, later Wentworth (J. Austen)" , "Female name" , "Henry VIII's fourth wife" , "British queen" , "One of two Henry VIII wives" .)
