Continued existence of frail feet, sadly (9)
I believe the answer is:
afterlife
'continued existence' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'frail feet sadly' is the wordplay.
'sadly' is an anagram indicator.
'frail'+'feet'='frailfeet'
'frailfeet' with letters rearranged gives 'AFTERLIFE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for afterlife that I've seen before include "Post-death existence" , "Existence following death" , "Hoped-for future" , "paradise" , "Existence beyond the grave" .)
