As used when traveling in Bruges? (3)
I believe the answer is:
Here is my best explanation:
'as used when traveling in bruges?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'in bruges?' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RUG' is hidden in the letters of 'bruges'.
(Other definitions for rug that I've seen before include "A floor covering", "Thick floor-mat or coverlet", "Hairpiece", "Floor-mat", "wrap", "Piece of floor covering", "Small carpet", "Thick mat", "A bug may be snug in it" and "Mat or knee-cover".)
