She creates a new way to finish off the stock list (8)
I believe the answer is:
inventor
'she creates a new way' is the definition.
I can't tell whether this definition defines the answer.
'finish off the stock list' is the wordplay.
'finish off' means to remove the last letter.
'the stock list' becomes 'inventory' ('inventory' can be a synonym of 'stock list').
'inventory' with its final letter taken away is 'INVENTOR'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for inventor that I've seen before include "Creative person" , "Discoverer" , "Author" , "Bell, say" , "Creator of new devices" .)
