With just one article, she upsets the male (6)
I believe the answer is:
amelia
'the male' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I don't see?
'with just one article she upsets' is the wordplay.
'with just one article' becomes 'ail' (I am not sure about this - if you are sure you should believe this answer much more).
'she' becomes 'ema'.
'upsets' says the letters should be written backwards.
'ail'+'ema'='ailema'
'ailema' back-to-front is 'AMELIA'.
Can you help me to learn more?
(Other definitions for amelia that I've seen before include "Fielding novel" , "Bloomer maybe" , "I, a male (anag) - a woman" , "Fielding heroine" , "-- Earhart, US aviation pioneer" .)
