The Spanish aristocrat does sweet decorations for funeral (4,7)

'sweet decorations for funeral' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'the spanish aristocrat does' is the wordplay.
'the spanish' becomes 'las' (plural form of 'the' in Spanish).
'aristocrat' becomes 'toff' (toff can mean an upper-class person).
'does' becomes 'ices' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'las'+'toff'+'ices'='LAST OFFICES'

Can you help me to learn more?
