Staggered to get label (3)
I believe the answer is:
tag
'label' is the definition.
(I know that label can be written as tag)
'staggered to get' is the wordplay.
'to get' says the answer is hidden in the clue (I've seen 'gets' mean this).
'TAG' is hidden within 'staggered'.
(Other definitions for tag that I've seen before include "Refrain" , "Tab" , "Restriction" , "Tie-on label" , "flap" .)
