Some put here incorrectly, which should be in that place (7)
I believe the answer is:
therein
'in that place' is the definition.
(I've seen this before)
'some put here incorrectly which' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'THEREIN' can be found hidden inside 'put here incorrectly which'.
'should be' is the link.
(Other definitions for therein that I've seen before include "Neither (anag) - into that" , "in that respect" , "Inside that" , "enclosed by that place?" .)
