nana

[Lynne Murphy]

One of my English colleagues has a "Nana", so I think that the East European
and WASP sources are probably separate.  (She used it as a generic term in our
convesation--'my nana loved the theatre'.)
It may just be like 'mama'--present in many langauges but not necessarily
from the same source---seems a natural alteration of  'mama' to indicate
another generation.

But pop-pop (pron. pupup) seems more particular to the US.
