As there has been some snow here this week, and it’s snowing at bit as I write this, I thought I’d look at some words for snow.
In Romanian snow is zăpadă [zəˈpadə], which comes from the Slavic word zapadati (to fall) [source]. To snow is a ninge, and snowfall is ninsoare, which both come from the Latin ningere (to snow), utimately from the Proto-Indo-European *sneygʷʰ- (to snow) [source].
The English word snow comes from Middle English snow/snaw, from the Old English snāw (snow), from the Proto-Germanic *snaiwaz (snow), from the Proto-Indo-European *snóygʷʰos (snow), from the root *sneygʷʰ- (to snow).
Many of the words for snow in other European languages come from the same Proto-Indo-European root. However, words for snow in Welsh (eira), Cornish (ergh) and Breton erc’h, come from the Proto-Celtic *argyos (white), via the Proto-Brythonic *ėrɣ (snow) [source].
