Katuic languages
language family
The fifteen Katuic languages form a branch of the Austroasiatic languages spoken by about 1.5 million people in Southeast Asia. People who speak Katuic languages are called the Katuic peoples. Paul Sidwell notes that Austroasiatic/Mon–Khmer languages are lexically more similar to Katuic and Bahnaric the closer they are geographically. He says this geographic similarity is independent of which branch of the family each language belongs to. He also says Katuic and Bahnaric do not have any shared innovations, so they do not form a single branch of the Austroasiatic family, but form separate branches.
Classification
In 1966, a lexicostatistical analysis of various Austroasiatic languages in Mainland Southeast Asia was performed by Summer Institute of Linguistics linguists David Thomas and Richard Phillips. This study resulted in the recognition of two distinct new subbranches of Austroasiatic, namely Katuic and Bahnaric (Sidwell 2009). Sidwell (2005) casts doubt on Diffloth's Vieto-Katuic hypothesis, saying that the evidence is ambiguous, and that it is not clear where Katuic belongs in the family. Sufficient data for use in the sub-classification of the Katuic languages only become available after the opening of Laos to foreign researchers in the 1990s.

Why this record matters
“Katuic languages” is worth following because a concise public description often conceals a longer documentary argument. Here, Katuic, languages and language provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 29, 2026. The linked authority identifier is Q56697. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1966, 2009 and 2005.
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.
