"The Faerie Queene" woman whose name means "peace" (5)
I believe the answer is:
irena
'the faerie queene woman whose name means peace' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for irena that I've seen before include "Girl's name; Raine (anag.)" , "Miss" , "Foreign woman" , "Girl" .)
