Etymology
From, from. Baltic cognates include 🇨🇬, 🇨🇬, 🇨🇬. Indo-European cognates include 🇨🇬, 🇨🇬, 🇨🇬, 🇨🇬.

The initial v- is typical for East-Baltic cognates and plausibly comes from an undetermined particle; various theories suggest Lithuanian (genitive plural) or Baltic *ve / *vi- (“particularly”), from Proto-Indo-European.
