Stocking maker is hero in the making (6)
I believe the answer is:
hosier
'stocking maker' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'is hero in the making' is the wordplay.
'is hero' anagrams to 'HOSIER'.
However, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for hosier that I've seen before include "Maker or dealer in stockings" , "Manufacturer or seller of stockings" , "tight merchant" , "Shopkeeper who sells stockings" , "Dealer in socks and stockings" .)
