Languages written right to left

Arabic and Hebrew are familiar right-to-left scripts. Direction describes the script’s layout; a language may have relationships with scripts written in different directions. Mixed text and numbers need the Unicode Bidirectional Algorithm, not simply reversed character order.

Scripts and language records to explore

A curated starting set, not a complete ranking or a claim of contemporary use. Relationships below use GlotScript multiple-source attestation; direction uses the bundled CLDR-derived script metadata. Regions, dates and official status are not inferred.

For mixed-direction web content, use semantic language tags and dir="auto" where appropriate; <bdi> can isolate an unknown-direction name. Test punctuation, numerals and combining marks rather than inserting directional controls without understanding their effect.
