Passamaquoddy (Peskotomuhkati)1. About Passamaquoddy
Passamaquoddy (Peskotomuhkati) is an Eastern Algonquian language of eastern Maine and southwestern New Brunswick.2
It is a dialect of the same language as Maliseet (together: Maliseet-Passamaquoddy / Wolastoqey-Peskotomuhkati), critically endangered. Confidence: High for classification; Medium for speaker figures.
2. Where it sits in the family
Passamaquoddy and Maliseet are mutually intelligible dialects of one Abenakian Eastern Algonquian language.
3. Writing & shared features
Like the other Eastern Algonquian languages, Passamaquoddy is (or was) written with a Latin-based orthography developed with its community, and shares the family's hallmark structure: polysynthesis (long verb-words), an animate/inanimate gender system, and obviation (the proximate–obviative or ‘fourth person’ contrast). See the family overview for these shared features.1
4. A few community-sourced words

5. A remarkably well-documented language
Passamaquoddy has one of the richest documentation records of any Eastern Algonquian language. A modern dictionary was begun in the 1970s by the linguist Philip S. LeSourd, working with the bilingual-education program at Indian Township, Maine.3 Through decades of collaboration with the first-language speaker David A. Francis and the linguist Robert M. Leavitt it grew into the roughly 18,000-entry Passamaquoddy-Maliseet Dictionary (2008), now openly available and still expanding as the Peskotomuhkati–Wolastoqey Language Portal.34 A two-volume second edition with more than 19,000 entries, a grammatical sketch and verb-conjugation guides was published by the University of Maine Press in 2026.7
6. Speakers and vitality
The language is critically endangered. Only a few hundred people speak it fluently, most of them older adults, and it is listed on the Endangered Languages Project.8 Community-led programmes — bilingual education at Indian Township and Sipayik (Pleasant Point), immersion efforts, and the recordings gathered on the language portal — are working to carry it to younger generations.8
7. How the language is built
Passamaquoddy is polysynthetic and largely agglutinative: words are assembled from strings of meaningful pieces, and a single verb can express what English needs a whole clause to say. Every noun is either animate or inanimate, and verbs come in matching classes — intransitive verbs that agree with an animate or inanimate subject, and transitive verbs that agree with an animate or inanimate object (the categories linguists label AI, II, TA and TI).5 Like other Algonquian languages it is direct–inverse: instead of fixed subject and object endings, the verb marks who acts on whom according to a ranking of the participants.56
8. Learning with community resources
The Peskotomuhkati–Wolastoqey Language Portal is the central resource for learners: a searchable dictionary with audio from fluent speakers, plus guides to noun and verb forms.4 The Endangered Languages Project hosts community-linguist charts of the noun and verb systems.5 Any fuller course on LinguaCommons should be built with Passamaquoddy educators using these community-endorsed materials.
Status of this guide
This orientation covers Peskotomuhkati and its relation to Maliseet, plus one community word. A fuller course should use the Passamaquoddy-Maliseet Portal and community educators.
⚑ Requires community review before publication. This is an Indigenous language; any expansion should use community-authored and community-endorsed sources, respect the community’s preferred orthography, and avoid culturally sensitive material unless a community source presents it for learners.
Honest limitations
- Passamaquoddy and Maliseet are one language; they are listed separately here per the requested entry list.
- Most Eastern Algonquian languages are dormant or endangered; documentation quality varies and this guide is an honest orientation, not a full course.
- Requires community review before publication (see above).
- This is an orientation stub; a fuller community-led course is not yet built.
