hreflang="nv"

nv is a valid hreflang value for Navajo.

Language: Navajo (nv, ISO 639-1)

Example

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

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

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