Cooker fix? It's applied at last (7)
I believe the answer is:
hobnail
'applied at last' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'cooker fix?' is the wordplay.
'cooker' becomes 'hob' (I can't explain this - if you can you should believe this answer much more).
'fix?' becomes 'nail' (I've seen this before).
'hob'+'nail'='HOBNAIL'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for hobnail that I've seen before include "One keeping shoes on" , "Walk over roughly" , "Stud on boot" , "Stud for boots" , "Protection for the sole of a heavy boot" .)
