First resident of the White House (5)
I believe the answer is:
adams
'first resident of the white house' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for adams that I've seen before include "Richard --, Watership Down author" , "Ansel --, US landscape photographer" , "revolutionary leader" , "Sort of apple" , "Douglas - (The Hitchhiker's Guide to the Galaxy)" .)
