Set great store by (7)
'store by' is the definition.
'hoard' can be an answer for 'store' (hoarding is a kind of storing). I'm not sure about the 'by' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hoard that I've seen before include "Cache" , "Store of money etc, often hidden" , "Accumulated store" , "Amass secretly" , "Collection" .)
'set great' is the definition.
I can't tell whether this defines the answer.
'store by' is the wordplay.
'store' becomes 'hoard' (hoard is a kind of store).
'by' becomes 'ed' (I can't explain this - if you can you should believe this answer much more).
'hoard'+'ed'='HOARDED'
