An open-source auxiliary language

A language built to be understood the first time.

Sorantoki (lit. “sun speak”) is a deliberately minimal international auxiliary language: fixed word order, ten consonants, a six-slot verb chain, and no irregular forms to memorize. Designed to be simple, clear, and kind to learners — and, when you want it, warm.

Hover a word

Sorantoki wh-words and constituents never move from where the answer would go — so an interlinear gloss reads left to right, exactly in speaking order. Try it:

tap / hover each word for its gloss
miI wanwant [modal] rapiriquickly peserobe‑taught poin order to kanbe able to tokispeak konwith mutaneveryone
“I want to be taught quickly in order to speak with everyone.”
Your first word

wasa

“I didn’t catch that” — unclear hearing, unclear speech, or simply unclear understanding.

wasa is a gentle, non-blaming way to ask someone to repeat, slow down, or clarify. It signals cooperation, not error. In Sorantoki culture, communication is shared responsibility: if something isn’t understood, the listener uses wasa without hesitation, and the speaker repeats without feeling corrected. Use it any time you need clarity — it keeps conversations friendly, patient, and clear.

Pronounced wasa, vasa, watha, or vatha — all equally correct.

Why Sorantoki

Three things rarely designed together

01

Structural simplicity

No inflection or irregular forms. Fixed SVO word order and a logical six-slot serial verb template. A small phoneme inventory with no consonant clusters.

02

Inclusive design

Multiple pronunciation variants are equally correct. A single stress rule with no exceptions. Optional clarity markers instead of mandatory precision — and a cultural repair word that removes blame from misunderstanding.

03

Open, organic evolution

No central academy or governance board. Released under permissive licenses so the community can use, adapt, and grow it based on real-world need — driven by usage, not committee votes.

Two registers, one grammar

Clear Register & Warm Register

Sorantoki recognises two usage styles, not two languages. Both share identical grammar and full mutual intelligibility — a speaker may shift between them within a single sentence. The toggle in the navigation bar switches this entire site between them the same way.

tu pon ka? — “Are you okay?”

Used for teaching, instructions, documentation, and precision. Minimal or no stance particles. Focus on clarity and efficiency. The question marker ka is mandatory.

tu pon nu? — “Are you okay?” (gentle, caring)

Used for daily life, care, friendship, family, and emotional speech. Allows stance particles like nu and ma, expressive reduplication, and phonetic softening. Focus on connection and trust.
