Etymology
From a Hellenisation of earlier, from the root. Cognate with 🇨🇬, 🇨🇬,, 🇨🇬, and perhaps or 🇨🇬.

According to De Vaan citing Szemerényi, perhaps from an s-stem. However, De Vaan finds both the -él- > -ól- and -os > -ur changes to be irregular (for -ol- > -ul- see ), adding that perhaps it comes from, from an r/n-stem instead.
