Build languages
with intention
A complete toolkit for designing constructed languages. From phoneme inventories to syntax rules, create languages that feel authentic and internally consistent.
What you can build
Every component of a language, systematically organized.
Phonology
Define consonants, vowels, and suprasegmentals. Set up allophonic rules, phonotactic constraints, and syllable structures.
Morphology
Create grammatical categories like case, number, and tense. Define morphemes, affixes, and inflection paradigms.
Syntax
Establish word order rules, phrase structures, and transformations. Document how sentences are constructed.
Lexicon
Build your vocabulary with definitions, etymology, semantic fields, and relationships between words.
Writing Systems
Design scripts from alphabets to logographies. Define glyphs, romanization rules, and rendering options.
Texts
Write and translate texts with interlinear glossing. Build a corpus that demonstrates your language.
Tools that accelerate your work
Beyond documentation, Conlanger provides computational tools that help you generate, analyze, and evolve your language.
Collaborate in real-time
