Around Ponders End, plenty goes missing! (4)
I believe the answer is:
lost
'missing' is the definition.
(similar in meaning)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for lost that I've seen before include "at sea" , "See 8" , "Not recognising one's whereabouts" , "See 10" , "Unable to find one's way" .)
