Crossword Genius

Dean not including verse in passage (5)

Ross

I believe the answer is:

alley

'passage' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for alley that I've seen before include "Narrow lane; type of cat" , "Narrow back street" , "Back lane" , "Marble" , "Bowling lane" .)

I've seen this clue in The Times.
