Charm everybody, yet finish a failure (6)
I believe the answer is:
allure
'charm' is the definition.
(I've seen this in another clue)
'everybody yet finish a failure' is the wordplay.
'everybody' becomes 'all' (I've seen this in another clue).
'yet' becomes 'ur' (I can't justify this - if you can you should give a lot more credence to this answer).
'finish' says to take the final letters.
The last letter of 'failure' is 'e'.
'all'+'ur'+'e'='ALLURE'
Can you help me to learn more?
(Other definitions for allure that I've seen before include "Seduction" , "Tempt" , "Transport" , "There's glamour" , "Powerful fascination" .)
