Quaker's "you" (4)
I believe the answer is:
thee
'quaker's you' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for thee that I've seen before include "Quaker 'you'" , "You (arch.)" , "You in the olden days" , "Old objective second person singular" , "you many years ago" .)
