Depreciate after I'm gone? (5)

I believe the answer is:
decry
'depreciate' is the definition.
(thesaurus)
'i'm gone?' is the wordplay.
I cannot quite see how this works, but
'gone?' could be 'dec' (abbreviation for deceased) and 'dec' is present in the answer.
This explanation may well be incorrect...
'after' acts as a link.
Can you help me to learn more?
(Other definitions for decry that I've seen before include "Disparage, regard as unimportant" , "Belittle or disparage" , "Publicly denounce" , "Disparage, criticise" , "Run down" .)
