Frisii

Frisii pl (plural only)

1. (historical) A tribe of Northern Germany who dwelt between the rivers Rhine and Ems.

Possibly named for their curly hair, from Proto-Germanic *frisaz (“curly, frizzy”), which might possibly be from Proto-Indo-European *prews-, which Pokorny says means to burn as well as to freeze (see Sanskrit प्लोषति (ploṣati)). If valid, this could derive from the warping of objects under temperature extremes.
