Second-hand dealer's wobbles when walking (7)
I believe the answer is:
totters
'dealer's wobbles when walking' is the definition.
I can't judge whether this definition defines the answer.
'second-hand' is the wordplay.
I cannot really understand how this works, but
'second' could be 's' (common abbreviation) and 's' is found in the answer.
'hand' could be 'r' (abbreviation for right, as in the right-hand side) and 'r' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for totters that I've seen before include "Collector of bones" , "Scrap dealers" , "reels" , "Walks hesitantly" , "salvage-collectors" .)
