Crossword Genius

Hoard one hundred yen (5)

Ross

I believe the answer is:

cache

'hoard' is the definition.
('cache' can be a synonym of 'hoard')

'one hundred yen' is the wordplay.
'one hundred' becomes 'c' (Roman numeral).
'yen' becomes 'ache' ('ache' can be a synonym of 'yen').
'c'+'ache'='CACHE'

(Other definitions for cache that I've seen before include "Secret source" , "Hiding place for treasure or store" , "Reserve" , "Conceal" , "Hidden storage space" .)

I've seen this clue in The Times.
