Constructed Language Word Generator

What makes an invented language feel like one language rather than a pile of noises is consistency: the same sounds, the same syllable shapes, the same things allowed and forbidden throughout. So the sound system here is yours. Type the consonants, the vowels and what a syllable may close on, tick the shapes a syllable may take, and set how long a word runs. Every word that comes back is then read again from its letters alone and taken apart into syllables built only from what you listed — so a word you could not have made never reaches you.

Consonants

Separated however you like. A pair or trio of letters counts as one consonant, so tl and sh are each one sound.

Vowels

Every syllable takes exactly one of these. A vowel pair such as ai counts as one.

Endings

What a syllable may close on, used only by the shapes that end in a consonant.

Syllable shapes

Which shapes a syllable may take. A shape you leave unticked never appears in a word.

V — a bare vowel, as in a-

CV — consonant then vowel, as in ka

VC — vowel then ending, as in ak

CVC — consonant, vowel, ending, as in kan

Shortest word

In syllables.

Longest word

In syllables.

How many words

Each is paired with a different everyday meaning.

Repeat word (optional)

Leave it empty and one is chosen for you. It appears in the address bar, so the same link with the same sound system gives back the same vocabulary — which is what a language built over several sittings needs.

Your vocabulary will appear here.

What this generator does

Builds each word syllable by syllable from the inventory you declared, in the shapes you ticked, and pairs each with an everyday meaning so the result reads as a vocabulary rather than a column of sounds. It also tells you how many different words your rules allow altogether, which is usually the surprise: a couple of dozen fragments reach into the millions.

How to use this tool

Type your consonants, vowels and endings. A pair or trio of letters counts as one sound, so sh and tl are each one consonant.
Tick the syllable shapes your language allows and set how many syllables a word may run to.
Build the words, and read the syllable division shown beside each one.
Copy the link to come back to the same vocabulary, or the text to take the sound system with you.

Understanding the controls

Consonants: What a syllable may start with, separated however you like. A pair or trio of letters counts as one consonant, so sh, th and tl are each a single sound.
Vowels: Every syllable takes exactly one. A vowel pair such as ai or ou counts as one.
Endings: What a syllable may close on. Only the shapes that end in a consonant use these, so a language of open syllables can leave the box empty.
Syllable shapes: Which shapes a syllable may take — a bare vowel, consonant-vowel, vowel-ending, or all three parts. A shape you leave unticked never appears.
Shortest and longest word: In syllables. One syllable reads as everyday vocabulary; three or four read as names or formal terms.
How many words: Each is paired with a different everyday meaning, so no two entries share a word.
Repeat word: The word this vocabulary was built from. The same link with the same sound system gives back the same words, which is what a language built over several sittings needs.

Common use cases

Starting a constructed language from a sound system you chose rather than one you were given
Keeping place and character names in a setting sounding like they belong to one another
Teaching phonotactics with words a class can check against the rules on the board
Trying a sound system out before committing to it — change one list and see what it does
Coming back to the same vocabulary over several sittings from one link

How this generator works

The check takes the finished word as a string and re-derives a division of it into syllables, using nothing but the rules you set. It never looks at how the word was assembled, so a builder that produced something it had no right to produce could not hide behind its own record of what it did. Where a word can be divided in more than one way — which written syllables genuinely can be — one division that obeys your rules is shown, because that is the claim the rules actually support.

Randomness and fairness

Words are built from a repeat word taken from your browser’s secure generator unless you type one of your own, so a link brings back the same vocabulary. A repeat word is there to make a vocabulary reproducible and is not a security measure; nothing here is suitable for anything that has to stay secret.

For how randomness is produced across the whole site, see how Generate Random works.

Limitations and good to know

These are invented sounds. No real language is described, translated or drawn on, and the meanings are attached arbitrarily — a word here does not mean what it is paired with in any language anyone speaks.
The rules govern spelling rather than pronunciation, so how a word sounds is up to the reader.
There is no morphology, so these are roots. Nothing is inflected, compounded or derived from anything else.
Stress and tone are not modelled, and both do a great deal of work in how a real language sounds.
Whatever inventory you give it, no word runs to three identical letters, more than three vowels or three consonants together, or past thirteen letters. Those limits are what keep a word readable and they cannot be turned off.
Sounds are written as letters, so a distinction English spelling cannot make is one this cannot make either.

Privacy and your data

Your sound system and the words built from it stay in your browser: nothing you type is transmitted, stored or measured. The repeat word is a short label this page minted or you typed, and it is the only thing that appears in the address.
