There is no single authoritative public list of the '100 most widely spoken languages': published rankings differ in how they count second-language (L2) speakers, how they split or merge macrolanguages and varieties (e.g. Arabic, Chinese, Persian, Serbo-Croatian, Hindi and related languages), and in the census data they rely on. The entries tagged 'top-100-seed' were compiled from widely published total-speaker (L1+L2) rankings, such as the summaries Ethnologue publishes, and are a seed list only. TODO: this seed list has NOT yet been reconciled against a single cited, dated dataset; until it is, the tag means 'appears in commonly published top-100 rankings', not 'verified rank'. No speaker counts are recorded here. Further entries were added so that (a) every UN member state has at least one entry for a language it designates as official or uses as its national/administrative language ('national-official'; 'un-official' marks the six official languages of the United Nations), (b) Modern Standard Arabic and major spoken Arabic varieties are represented ('variety', with variantOf pointing to the standard), and (c) a selection of regional and Indigenous languages from every inhabited continent is included ('regional-indigenous'). Inclusion in this registry says nothing about translation availability: see translationStatus and reviewStatus. Tags follow BCP 47 as used by Unicode CLDR; see docs/i18n/language-registry.md.
