Cleric's tunic (3)
I believe the answer is:
alb
'cleric's tunic' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for alb that I've seen before include "White garment worn by priests" , "Without hindrance" , "Long white robe worn by proest" , "Priestly garment" , "Long white robe worn by Christian priest" .)
