Stockpile great crowd heard of (5)

Ross

I believe the answer is:

hoard

'stockpile' is the definition.
(I've seen this before)

'great crowd heard of' is the wordplay.
'great crowd' becomes 'horde' (I've seen this before).
'heard of' shows a homophone (sound like).
'horde' sounds like 'HOARD'.

(Other definitions for hoard that I've seen before include "(Miser's) store" , "Accumulated store" , "Cache" , "Secret store of valuables" , "Squirrel away" .)

I've seen this clue in The Times.
