hreflang="ie"

ie is a valid hreflang value for Interlingue.

Language: Interlingue (ie, ISO 639-1)

Example

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

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

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