What's the PIE for louse's egg, nit?
Latin lens
Latvian gni~da
Lithuanuan glinda
Irish sned, gnit
Welsh nedd
Grk konis "dust"
OE hnitu = OHG hniz < PGerm *hnito:
Albanian theni
Armenian anic
Russian gnida (Other Slavic
equivalents?)
It seems to exist a lot of corrupted variations of
the same base.
I'd try to explain Latin as
*gnNd- (or knNd-) > gnend- > nend->
dissimilation > lend-. PIE *gnNd- (or knNd-) can explain Latvian, Lithuanina
(dissimilated)
Other words point to a *gnid-.
Greek, Germanic and Albanian point to a
*k^nid-.
