Lots may get mislaid (4)
I believe the answer is:
lost
'mislaid' is the definition.
('lose' can be a synonym of 'mislay')
'lots may' is the wordplay.
'lots' anagrams to 'LOST'.
Though, I am unsure how the anagram is indicated.
'get' is the link.
Can you help me to learn more?
(Other definitions for lost that I've seen before include "Forgotten; misplaced" , "Baffled" , "Unable to find one's way" , "Not knowing one's whereabouts" , "Unable to be found" .)
