Polly or Pittypat (4)
I believe the answer is:
aunt
'polly or pittypat' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aunt that I've seen before include "Parent's female sibling" , "Family member" , "Tuna (anag.)" , "Wife of one's uncle" , "Close relative" .)
