Nakedly tell off Tina Fey? (5)
I believe the answer is:
elfin
'fey?' is the definition.
(I know that elfin can be written as elfin)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for elfin that I've seen before include "Delicate, slight" , "Small, mischievous and charming" , "Describing Santa's helpers" , "puckish" , "Small and fragile" .)
