Scrape mark, small, on end of sleeve (5)
I believe the answer is:
scuff
'scrape' is the definition.
(scuffing is a kind of scraping)
'small on end of sleeve' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'end of sleeve' becomes 'cuff' (I've seen this before).
's'+'cuff'='SCUFF'
'mark' is the link.
(Other definitions for scuff that I've seen before include "drag, while walking" , "Scrape (shoe, etc)" , "Scrape (eg, a shoe)" , "Scrape (shoes) when walking" , "Scrape (shoe leather)" .)
