Well I for one found that to be exceedingly interesting! In the
Yup'ik Eskimo language "apa" is grandfather, "ata" is father,
while "apii" and "atii" would be "his grandfather" and "his
father" respectively.
A paternal uncle is "ataata", which is also a stepfather.
Also the words are not necessarily literal. Not only my
grandchildren call me Apa Flo, so do my children and practically
everyone else I know who speaks Yup'ik (which I only know a few
words of...).
