Lallygag (6)
I believe the answer is:
linger
'lallygag' is the definition.
(I know that lallygag can be written as linger)
This is the entire clue.
(Other definitions for linger that I've seen before include "Remain behind" , "Leave slowly and hesitantly" , "Stay on as if reluctant to leave" , "Dally, stay on" , "Dawdle, hang around" .)
