Source-derived summary

Tlacolula Valley Zapotec or Valley Zapotec, known by its regional name Dizhsa, and formerly known by the varietal name Guelavia Zapotec (Zapoteco de San Juan Guelavía) is a Zapotec language of Oaxaca, Mexico.

Tlacolula Valley Zapotec is a cluster of Zapotec languages spoken in the western Tlacolula Valley, which show varying degrees of mutual intelligibility. All varieties of Valley Zapotec are endangered. The languages in this group include:

Santa Ana del Valle Zapotec

Teotitlán del Valle Zapotec

San Lucas Quiaviní Zapotec

Tlacolula de Matamoros Zapotec

San Juan Guelavía Zapotec

San Jerónimo Tlacochahuaya Zapotec

San Juan Teitipac Zapotec

Teotitlán del Valle dialect is divergent, 59% intelligible to San Juan Guelavía proper. Valley Zapotec is also spoken in the city of Oaxaca, capital of the state of Oaxaca.

In April 2014, linguist Brook Danielle Lillehaugen, along with students from Haverford and Swarthmore Colleges, visited Tlacolula de Matamoros to present an online Tlacolula Valley Zapotec talking dictionary to local leaders. It was estimated that about 100 elderly speakers of this Zapotecan language remain.

Tlacolula Valley Zapotec is a VSO language.

Editorial analysis

Why this record matters

The phrase “a cluster of Zapotec languages spoken in the western Tlacolula Valley” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q5614751. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
