A girl from Poland or Armenia (4)
I believe the answer is:
dora
'a girl' is the definition.
(girl's name)
'from poland or armenia' is the wordplay.
'from' indicates the answer is hidden within the clue.
'DORA' is hidden in the letters of 'poland or armenia'.
(Other definitions for dora that I've seen before include "David Copperfield's 'child-wife'" , "Bryan" , "This girl" .)
