Rests in which Warhol ultimately invested? (6)
I believe the answer is:
easels
'invested?' is the definition.
The answer and definition are not the same part of speech.
'rests in which warhol ultimately' is the wordplay.
'rests' becomes 'eases' ('ease' can be a synonym of 'rest').
'in which' indicates putting letters inside.
'ultimately' indicates one should take the final letters.
The last letter of 'warhol' is 'l'.
'eases' going around 'l' is 'EASELS'.
(Other definitions for easels that I've seen before include "Leases (anag)" , "Leases them out to artists" , "Supports in the studio" , "Artists' supports" , "Stands for blackboards, artists' paintings etc" .)
