The Pig Latin translator above moves the opening consonants of each word to the end and adds a suffix, which is the whole rule. It also runs backwards, which is the part most translators skip, because reversing the transformation needs a little more care than applying it.
Arb Digital built the reverse direction properly rather than leaving it out. Undoing the move means deciding how many letters to bring back to the front, and there is usually more than one answer that looks plausible. The tool resolves it by preferring the largest trailing group that is a legal way for an English word to begin, which gets clusters like "tr" and "str" right instead of returning one letter and producing nonsense.
What This Pig Latin Translator Does
Dictionary.com's entry for pig Latin describes it as a form of language derived from ordinary English by moving the first consonant or consonant cluster of each word to the end and adding an -ay sound, with a first recorded use dated to the 1840s. That is exactly the rule implemented here, and the phrase "or consonant cluster" is the part that separates a correct implementation from a naive one.
Words beginning with a vowel have no consonants to move, so they take a suffix instead. There is no single agreed choice: "way", "yay" and plain "ay" are all in common use, and the tool offers all three because none of them is the standard. Whichever you pick is applied consistently, which matters if you intend to translate back.
The default here is "yay", and the reason is reversibility. Under "way", every word beginning with w produces the same Pig Latin as a vowel word: "world" and "orld" both give "orldway", so w-words cannot be recovered. Under "yay" the collision moves to words beginning with y, so "yellow" and "ellow" both give "ellowyay". Plain "ay" is worse than either, because any vowel word ending in a consonant collides with a consonant word: "eat" and "tea" both give "eatay". Since w-initial words are far more common in English than y-initial ones, "yay" loses the least, and the round trip indicator tells you when your text has hit the remaining case.
Capitalisation is preserved by position rather than by letter. If the original word began with a capital, the translated word begins with a capital and the moved letters become lower case, so "Hello" gives "Ellohay" rather than "elloHay". Punctuation, digits, line breaks and spacing all pass through untouched, because only runs of letters are treated as words at all.
How to Use It
- Set the direction. Translating Pig Latin as though it were English produces a comical second layer rather than an error, so it is worth checking.
- Choose the vowel-word suffix first. Changing it afterwards changes every vowel-initial word, and a text encoded with one suffix will not decode cleanly with another.
- Paste your text. Everything that is not a letter is preserved in place, so paragraphs and punctuation survive intact.
- Watch the round trip indicator. It translates and immediately reverses, then compares against your input, so it reports on your actual text rather than making a general claim.
- Use the reverse-direction button to feed the output straight back in without retyping it.
The Formula: The Rule, Written Out
For each word, find the leading run of consonants. If that run is empty, the word starts with a vowel and takes the chosen vowel suffix. If it is not empty, move the entire run to the end of the word and add "ay".
Two refinements make the output match what people actually say. The letter u following q moves with it, so "queen" becomes "eenquay" and not "ueenqay", because "qu" behaves as a single unit in English. And a word-initial y is treated as a consonant while a y anywhere else is treated as a vowel, so "yellow" becomes "ellowyay" while "myth" becomes "ythmay".
Work the default. "pig latin translator" gives three words. In "pig" the leading consonant run is "p", so it moves to the end and the word becomes "igpay". In "latin" the run is "l", giving "atinlay". In "translator" the run is "tr", both letters, so the whole cluster moves and the word becomes "anslatortray". The complete output is "igpay atinlay anslatortray", and reversing it returns the original exactly.
Why Reversing Is the Hard Direction
Take "igpay" and strip the "ay". You are left with "igp" and a decision: bring back one letter to get "pig", or two to get "gpi". Both are mechanically valid; only one is a word. Take "anslatortray" and the same question has answers "ranslatort", "translator" and several worse ones.
A translator with no dictionary needs a rule, and the rule this tool uses is phonological rather than statistical. English permits only certain consonant sequences at the start of a word: "tr", "str", "shr", "qu" and a few dozen others are legal openings, while "gp", "tl" and "rn" are not. The decoder tries the largest trailing group first and accepts the first one that is a legal opening. For "igp" the two-letter option "gp" is not a legal English opening, so it falls back to "p" and returns "pig". For "anslatortr" the two-letter "tr" is legal, so it is preferred over "r" and returns "translator".
This works well and it is not infallible. Where two different English words genuinely produce the same Pig Latin, no rule can recover which was meant, and the round trip indicator will tell you when your specific text has hit such a case. That honesty is more useful than a decoder that silently guesses.
What Pig Latin Accidentally Teaches
Children who have never heard the word "phoneme" apply Pig Latin correctly to words like "street" and "throw", moving the whole cluster rather than a single letter. That is not something they were taught, and it is evidence that speakers represent the beginning of a syllable as a unit rather than as a string of letters.
Linguists call that unit the onset, and language games like this one are a standard piece of evidence for syllable structure being psychologically real. Introductory courses such as MIT OpenCourseWare 24.900, Introduction to Linguistics, are built around exactly that idea: that language is a complex but law-governed mental system whose rules speakers follow without being able to state them.
Two more clues sit in the same place. The rule is defined by sound rather than spelling in real use, which is why "hour" is a hard case: it is spelled with a consonant and pronounced with a vowel, and speakers disagree about which rule applies. And Pig Latin operates on words rather than letters, which is why it is a language game and not a cipher, and why it is far less regular than the substitution schemes in the Caesar cipher translator or the ROT13 encoder and decoder.
The Edge Cases This Tool Takes a Position On
Every Pig Latin implementation has to decide a handful of questions, and they are worth stating rather than leaving as surprises. Words with no vowel at all, such as "nth" or "rhythm" in some spellings, have a consonant run covering the whole word; moving all of it would leave nothing behind, so the tool leaves such words unchanged and counts them separately.
Hyphenated words are treated as two words, because the hyphen is not a letter, so "well-known" becomes "ellway-ownknay". Contractions keep their apostrophe in place for the same reason, which produces a slightly odd but reversible result. Words in other scripts and accented letters are left alone entirely, since the consonant and vowel rules are defined over the basic Latin alphabet only.
Single-letter words are the last case. The word "a" is a vowel word and takes the suffix, while "I" is a vowel word too, and both come back correctly. A single consonant such as an initial in a name has no vowel, so it is left as it stands rather than being turned into a two-letter fragment.

- Moving only the first letter — "street" becomes "eetstray", not "treetsay", because the whole cluster moves as one unit.
- Changing the vowel suffix between encoding and decoding — a text written with "way" will not reverse cleanly under "yay".
- Treating qu as two letters — the u travels with the q, so "queen" gives "eenquay".
- Assuming y is always a vowel — at the start of a word it behaves as a consonant and moves, and anywhere else it does not.
- Expecting it to hide anything — Pig Latin is a word game with a published rule, not a cipher, and it conceals nothing from a reader who knows it.

Frequently Asked Questions
Move the opening consonant or consonant cluster of a word to the end and add "ay". Words that begin with a vowel have nothing to move, so they take a suffix instead, usually "way" but sometimes "yay" or just "ay" depending on who you learned it from.
Because the whole opening cluster moves, not just the first letter. Speakers treat the consonants before the first vowel as a single unit, which is why every fluent speaker produces "eetstray" rather than "treetsay" without having to think about it.
Strip the suffix, then decide how many trailing letters belong at the front. This tool tries the largest group first and accepts the first one that is a legal English word opening, which recovers clusters like "tr" and "str" correctly instead of moving a single letter.
They have no consonants to move, so a suffix is added instead. There is no standard choice between "way", "yay" and "ay", so the tool offers all three and applies whichever you pick consistently throughout the text.
Both, depending on position. At the start of a word it behaves as a consonant and moves, so "yellow" becomes "ellowyay". Anywhere else it counts as a vowel, so "myth" has only "m" to move and becomes "ythmay".
Neither, in any useful sense. It is a language game with a short published rule, and it conceals nothing from anyone who knows the rule. It is far less regular than a substitution cipher, because it operates on words and their sounds rather than on individual letters.
Because two different English words can produce the same Pig Latin, and no rule without a dictionary can recover which one was meant. With the default yay suffix the remaining collision is words beginning with y, since yellow and ellow both give ellowyay. The indicator reports on the exact text you typed.
Punctuation, digits and spacing pass through in place, because only runs of letters are treated as words. A capitalised word stays capitalised at the front, so "Hello" gives "Ellohay" and not "elloHay".
