Grate fragment ending in fire (6)
I believe the answer is:
scrape
'grate' is the definition.
(I've seen this before)
'fragment ending in fire' is the wordplay.
'fragment' becomes 'scrap' (scrap is a kind of fragment).
'ending in' indicates one should take the final letters.
The final letter of 'fire' is 'e'.
'scrap'+'e'='SCRAPE'
(Other definitions for scrape that I've seen before include "Graze - awkward predicament" , "Scratch; just make (living)" , "Recaps about abrasion" , "Abrasion or mischievous excapade" , "Abrade in capers" .)
