Staggers; wobbles (7)
I believe the answer is:
totters
This clue is a double definition.
'staggers' is the first definition.
(I've seen this before)
'wobbles' is the second definition.
(tottering is a kind of wobbling)
(Other definitions for totters that I've seen before include "Scrap dealers" , "reels" , "Summer" , "Walks hesitantly" , "Walks unsteadily" .)
