Conlang Syllable & Phonotactics Checker

Free constructed-language phonotactics checker. Define your allowed syllable patterns (CV, CVC, CVCC…) and phoneme inventory, then test a list of invented names for consistency. Auto-generate compliant words.

Niet ontworpen voor Nederlands

Deze tool is gekalibreerd voor Engels (en enkele verwante talen). Resultaten in Nederlands zijn waarschijnlijk niet betekenisvol.

Wanneer gebruiken

Use when naming characters, places, or factions for a fictional language. Consistency is what makes invented names feel believable.

Vergelijking

PolyGlot is the heavyweight conlang tool but is desktop-only and complex. This tool covers the most common diagnostic — does my word fit my rules?

Enter your values below. Calculations run locally as you type.

Zo werkt het

You define allowed syllable patterns (CV, CVC, CVCC…) and the consonant and vowel inventories.

The checker greedily splits each test word into syllables matching one of your patterns. Words that fully tile are legal; the first illegal cluster is reported.

The generator builds 1–3 syllable words that obey the rules — useful when brainstorming city or character names.

Veelgestelde vragen

What syllable patterns are supported?

Any combination of C (consonant) and V (vowel). Multi-character consonants and vowels are matched greedily by longest match.

Does it handle digraphs (e.g., "th")?

Yes — list "th" as a consonant alongside "t" and "h". The matcher prefers the longest defined unit.

What does CV or CVC notation mean?

C stands for a consonant and V for a vowel, so CV is a consonant-vowel syllable like 'ka' and CVC adds a closing consonant like 'kat'. Listing your allowed patterns defines the phonotactics, or permissible sound structure, of your language.

What is a phoneme inventory?

It is the full set of distinct sounds your language uses, separated into consonants and vowels. The checker compares each test word against this inventory to flag sounds you never declared.

Voorbeeld

Invoer

Patterns: CV, CVC. Consonants: p t k m n s r l. Vowels: a e i o u. Test: aman, katira, mendor, xthun.

Uitvoer

3 of 4 fit (75%) — "xthun" has illegal cluster.

Aman = a-man (V-CVC) — wait, but you also need an onset for syllable 1; this is a deliberate edge case. The matcher fails on words that can't be split into your allowed patterns.

Veelgemaakte fouten

  • No support for tone, stress, or vowel harmony.
  • Greedy matching may favor a longer match when shorter would work.
  • Doesn't generate meaningful words — only phonologically valid ones.
