Member of the clergy from Slavic area (5)
I believe the answer is:
vicar
'member of the clergy' is the definition.
(I've seen this before)
'from slavic area' is the wordplay.
'from' indicates a hidden word.
'VICAR' is hidden in the letters of 'slavic area'.
(Other definitions for vicar that I've seen before include "Member of the clergy" , "Man with a dog collar" , "Goldsmith novel ''The . . . . . of Wakefield'' (5)" , "Parish incumbent" , "Serviceman" .)
