According to Rick Derksen, from Proto-Indo-European *sodós (“path”), perhaps from Proto-Indo-European *sed- (“to sit”). Cognate with Ancient Greek ὁδός (hodós, “way”).
Sergei Nikolaev believes that the comparison is “tempting, but unfounded phonetically,” which does not contradict the analogy in any way: The form has initial *x by analogy with derived words beginning with the prefixes *per-, *pri-, *u-, in which *s shifted to *x by the ruki sound law. But contradicts the Winter’s law.
According to Vladimir Dybo, the form is borrowed from Iranian (Dybo 2002: 479).
Frederik Kortlandt believes that the hypothesis of borrowing from Iranian is “semantically implausible” and the form goes back to *xodìti (Kortlandt 2007: 1). However, according to Nikolaev, it is accentologically implausible. According to ESSJa, reverse derivation is impossible, which supports the accentological argument.
Some dialect groups make it possible to reconstruct the semantic-accentuation pair: *xȍdъ, gen. *xȍda and *xòdъ, gen. *xodà. For example, this semantic-accentuation pair is represented in the Posozhko-Pripyat dialect: xod, gen. xódu, instr. xódom ~ xod, gen. xodá, instr. xodóm. Most other dialects usually retain one variant of the semantic-accentuation pair.
According to Nikolaev, the form is a secondary deverbative of *xodìti (Nikolaev 2012: 98).
