Fairy-like period piece (4)
I believe the answer is:
peri
This clue might be a double definition.
'fairy' is the first definition.
(Persian mythological being)
'period piece' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for peri that I've seen before include "Malevolent Persian spirit" , "Fairy queen" , "Beautiful fairy-like creature" , "Supernatural being in Persian folklore" , "Persian fairy or genie" .)
