so is a valid hreflang value for Somali.

Language: Somali (so, ISO 639-1)

Example

<link rel="alternate" hreflang="so" href="https://example.com/so/" />

The code is case-insensitive for Google. The conventional spelling is a lowercase language, a title-case script and an uppercase region: so.

Without a region, the annotation targets every Somali speaker regardless of country. Regional versions sit next to the language-only version in one cluster.
