A crowd of people, we hear, amass wealth (5)
I believe the answer is:
hoard
'wealth' is the definition.
(thesaurus)
'a crowd of people we hear amass' is the wordplay.
I cannot quite understand how this works, but
'a' is within the answer.
'crowd' could be 'd' and 'd' is present in the answer.
'of' could be 'o' and 'o' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hoard that I've seen before include "Squirrel away" , "Store, usually hidden" , "Stash of treasure" , "(Miser's) store" , "One's savings" .)
