Vengeful female upset blokes with English sibling! (7)
I believe the answer is:
nemesis
'vengeful female' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'upset blokes with english sibling' is the wordplay.
'upset' says the letters should be written backwards.
'blokes' becomes 'men' (bloke can informally mean a man).
'with' says to put letters next to each other.
'english' becomes 'E' (abbreviation).
'sibling' becomes 'sis' (short for sister).
'men' in reverse letter order is 'nem'.
'nem'+'e'+'sis'='NEMESIS'
Can you help me to learn more?
(Other definitions for nemesis that I've seen before include "Retributive justice" , "Agent of (someone's) downfall" , "rival who can't be beaten" , "Bane" , "The Greek goddess of divine retribution and vengeance" .)
