Γκρι, Grey, Gray

Both the Greek word Γκρι (Gri) and the English Grey (US gray) are borrowed from French Gris, from Old French Gris, from Proto-Germanic *grēwaz (“grey”). From there there are two main etymological suggestions.

a) from Proto-Indo-European *gʰregʰwos (“grey”), from Proto-Indo-European *gʰer- (“to glow, shine”), which produces a few other words like "grit" and "χρώμα". Also via Latin Grandis, the words "grand" and "great".

b) from Proto-Indo-European *ǵʰreh₁- (“to green, to grow”) which produces the words Grow and Gramen (Latin for grass) which carries on as grama in most Romance languages.
