Gravina (2014)

Gravina (2014) classifies Central Chadic as follows, as part of a reconstruction of the proto-language. Letters and numbers in parentheses correspond to branches in previous classifications.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—2014, 2006, 1977, 2019—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Mandara, languages and Afro-Asiatic.
Editorial analysis

Why this record matters

“Biu–Mandara languages” is worth following because a concise public description often conceals a longer documentary argument. Here, Mandara, languages and Afro-Asiatic provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 6, 2026. The linked authority identifier is Q2251547. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014, 2006, 1977 and 2019.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
