Vale where heroic figure finally slaughtered (7)
I believe the answer is:
cheerio
'vale' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'heroic figure finally slaughtered' is the wordplay.
'finally' suggests the final letters.
'slaughtered' indicates anagramming the letters.
The final letter of 'figure' is 'e'.
'heroic'+'e'='heroice'
'heroice' anagrammed gives 'CHEERIO'.
'where' acts as a link.
Can you help me to learn more?
(Other definitions for cheerio that I've seen before include "Bye-bye" , "for so long!" , "An informal hearty goodbye" , "Expression used when leaving" , "Say this before drinking" .)
