Scrape itchy lining out with abrasive (8)
I believe the answer is:
scratchy
'abrasive' is the definition.
(I know that abrasive can be written as scratchy)
'scrape itchy lining out' is the wordplay.
'scrape' becomes 'scratch' (synonyms).
'itchy lining out' becomes 'y' (I can't justify this - if you can you should believe this answer much more).
'scratch'+'y'='SCRATCHY'
'with' is the link.
Can you help me to learn more?
(Other definitions for scratchy that I've seen before include "Irritable" , "Itchy" , "after scoring" , "carelessly" , "marked by abrasions" .)
