Pass in orderly fashion at the far end, in files (5)
I believe the answer is:
rasps
'files' is the definition.
(I know this)
'pass in orderly fashion at the far end' is the wordplay.
'pass in orderly fashion' becomes 'asps' (I can't justify this - if you can you should believe this answer much more).
'at' says to put letters next to each other (I've seen this in other clues).
'end' indicates one should take the final letters.
The final letter of 'far' is 'r'.
'asps' put after 'r' is 'RASPS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for rasps that I've seen before include "Coarse files" , "Scrapes" , "Jars" , "fruit briefly" , "speaks hoarsely" .)
