But you would know him from Eve! (4)
I believe the answer is:
adam
'him from eve' is the definition.
'Adam' can be an answer for 'him'. I am unsure of the 'from eve' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for adam that I've seen before include "Father of Cain and Abel" , "First Christian ancestor" , "father of us all?" , "Man No. 1" , "First guy" .)
