hreflang="tn"

tn is a valid hreflang value for Tswana.

Language: Tswana (tn, ISO 639-1)

Example

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

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

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