Eve's husband (4)
I believe the answer is:
adam
'eve's husband' is the definition.
(in the Garden of Eden)
This is all the clue.
(Other definitions for adam that I've seen before include "Robert -, Sc. architect" , "who transformed Palladian architecture?" , "Robert-, eighteenth century Scots architect" , "first in the race?" , "__ Smith, author of The Wealth of Nations" .)
