Language Atlas
Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.
120 statements marked Debated.
Nubian, Proto-Language StatusNubian is not securely placed above the family level: older classifications put it within Nilo-Saharan under Eastern Sudanic, but Glottolog treats it as its own primary family pending conclusive evidence either way.

Ongota, Proto-Language StatusClassification is genuinely obscure: proposed variously as Cushitic, Nilo-Saharan, a language isolate, an independent branch of Afroasiatic, a pidginised creole, or East Cushitic with a Nilo-Saharan substratum; more recent assessments treat it as an isolate heavily influenced by neighboring languages.

Concerns Birth Year
Currently States -400
Panini's exact dates are unresolved. Scholarly estimates range across the sixth to fourth centuries BCE, with a fourth-century-BCE floruit (contemporary with the rise of the Mauryan Empire) the most commonly cited middle estimate; some place him as early as the sixth century BCE, contemporary with the Buddha. No date more precise than a range commands consensus.

Debated since the original 1913 Dixon and Kroeber proposal; some narrower groupings within it (Utian, Yok-Utian, Plateau Penutian) are more securely demonstrated than the phylum as a whole, and its unity remains disputed rather than established by the standard comparative method.

Concerns In Use Since (Year)
Currently States 1450
Genuinely disputed among scholars: proposed dates range from the 13th century, tied to the start of agricultural forest-clearing on the island, to as late as the 1770s, a hypothesis that the script was inspired by the 1770 Spanish annexation treaty and forgotten within a century. A 2024 Nature-published carbon-dating study of the Rome tablets found most dated to the 19th century, with one securely dated to the mid-15th century; that securely dated figure is recorded here as the best-attested physical date, not necessarily the invention date.

Sources diverge sharply on what is being counted. Ethnologues figure of roughly 16 million counts first-language speakers only; other widely cited estimates put total speakers, overwhelmingly second-language users of Swahili as an East African lingua franca, at well over 100 million, with some estimates as high as 200 million. There is no real dispute that Swahili has vastly more second-language than first-language speakers, only over how to weight that population in a single headline number.
