Man born of a mother? No! (4)
I believe the answer is:
adam
'man' is the definition.
(Adam is an example)
'a mother? no' is the wordplay.
'mother? no' becomes 'dam' (female parent of an animal. I am not sure about the 'no' bit.**).
'a'+'dam'='ADAM'
'born of' acts as a link.
(Other definitions for adam that I've seen before include "__ Smith, author of The Wealth of Nations" , "Scots. architect brothers" , "neoclassical style" , "First man of Genesis" , "Eves husband" .)
