Lapwing (6)
I believe the answer is:
peewit
'lapwing' is the definition.
(I know that lapwing can be written as peewit)
This is the entire clue.
(Other definitions for peewit that I've seen before include "Northern lapwing" , "Lapwing - ie wept (anag)" , "Kind of plover; let it weep" , "Does it weep, this bird?" , "Flighty type" .)
