Large seabird found among lost Arabs (9)
I believe the answer is:
albatross
'large seabird found among lost arabs' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for albatross that I've seen before include "Golf course achievement > accounting for handicap" , "Hole played in three strokes under par" , "Oceanic bird - golf score" , "Coleridge's marine bird." , "See 7" .)
