Just when beginning to adjudicate in points supporting First Lady (4,2)
I believe the answer is:
even as
'just' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'beginning to adjudicate in points supporting first lady' is the wordplay.
'beginning to' suggests taking the first letters.
'in' indicates putting letters inside.
'points' becomes 'Ns' (two compass points).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'first lady' becomes 'eve' (first woman in the Bible).
The first letter of 'adjudicate' is 'a'.
'a' placed inside 'ns' is 'nas'.
'nas' put after 'eve' is 'EVEN AS'.
'when' is the link.
Can you help me to learn more?
(Other definitions for even as that I've seen before include "a neighbouring number goes cycling?" , "At the moment" .)
