Square English archdeacon with no secret desires (4,3)
I believe the answer is:
even out
'square' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'english archdeacon with no secret desires' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'archdeacon' becomes 'ven' (abbreviation for The Venerable).
'with no secret desires' becomes 'out' (I can't explain this - if you can you should believe this answer much more).
'e'+'ven'+'out'='EVEN OUT'
Can you help me to learn more?
(Other definitions for even out that I've seen before include "Make level" , "Smooth" , "Make flat" , "Get level" , "iron?" .)
