Translate English to Pig Latin and back. Free Pig Latin generator with Standard / YAY / custom-suffix variants, decode mode, and per-word breakdown table.
A free bidirectional Pig Latin translator. Encodes English to Pig Latin using the standard rules (consonant clusters move to the end + "ay", vowels add "way" or "yay") with case and punctuation preservation. Decodes Pig Latin back to English on a best-effort basis (some Pig Latin words have ambiguous origins, so up to two candidate decodings are shown). Three variants: Standard (way / ay), YAY (vowel words use "yay"), and Custom (specify your own suffix). Live per-word breakdown table shows exactly how each word transforms. Built for kids, school projects, language games, and just-for-fun obfuscation.
Pig Latin is a language game — a systematic transformation of a natural language that preserves meaning while obscuring it. Its mechanism is morpho-phonological: it manipulates the onset of each syllable. The "consonant cluster moves to end + ay" rule is a specific kind of metathesis (consonant relocation), and the "way / yay" suffix on vowel-initial words is an artificial epenthesis (insertion of a meaningless syllable). Linguists study Pig Latin and other "ludlings" (language games) because they reveal what speakers know unconsciously about syllable structure: native English speakers automatically apply the rules to onsets, suggesting onsets are real units in the mental grammar even though English orthography doesn't mark them explicitly.
Pig Latin is one of many "secret languages" children invent. Verlan (French): syllables are reversed — "femme" → "meuf", "fou" → "ouf". Used in Parisian banlieue slang. Jerigonza (Spanish): each vowel is doubled with a P added — "hola" → "hopolapa". Ubbi-Dubbi (English, popular from PBS' Zoom show): each vowel gets a "ub" prefix — "hello" → "hubellubo". Salatí (Italian): syllable insertion of "ferpa" or similar. Nadsat (literary): the made-up slang in Anthony Burgess' Clockwork Orange, derived from Russian. Each language has produced its own ludlings, and they all serve the same social function: in-group bonding and adult exclusion.
Words that start with a consonant: move the initial consonant cluster to the end and add "ay". Example: "hello" → "ellohay", "string" → "ingstray" (move "str", add "ay"). Words that start with a vowel: add "way" or "yay" to the end. Example: "apple" → "appleway" (or "appleyay" in YAY variant). The letter "y" is treated as a consonant when it starts a word: "yellow" → "ellowyay". Capitalisation moves with the new first letter, and punctuation passes through unchanged.
Schoolyard slang dating back to at least the 1800s, with attestations in playground games and stage performances of vaudeville and Shakespeare adaptations. The earliest documented examples appeared in the 1860s. It became widely popular in the United States in the early 20th century as children's "secret language" — easy enough for kids to master but unintelligible to adults who hadn't learned the rules. Pop culture references abound: The Three Stooges, The Office (Michael Scott), Mickey Mouse, Looney Tunes, and even Thomas Jefferson reportedly used it in personal correspondence.
Pig Latin loses information when encoding consonant clusters. "ellohay" could decode back to "hello" (consonant cluster "h"), or to "shello" (cluster "sh"), or to "thello" — all valid Pig Latin encodings of different English words. The decoder shows the most likely candidate plus an alternate when the cluster is ambiguous. For known English text, decoding is usually unambiguous because most English consonant clusters are restricted (you can't start a word with "ngh", for example).
For words starting with a vowel, Standard variant adds "way" ("apple" → "appleway"), while YAY variant adds "yay" ("apple" → "appleyay"). Both are widely accepted; "way" is the more common formal variant taught in linguistics; "yay" is more common in spoken-word performance because the consonant onset is easier to articulate. The tool defaults to "way" but lets you switch.
Sort of — adults who didn't grow up with it often need a few seconds to decode a Pig Latin sentence. But the rules are simple enough that any literate adult can crack a paragraph in minutes. It's great for kids' games and casual obfuscation, but not for actual privacy. For real "hidden language" effects, look at constructed languages (Esperanto, Klingon) or actual encryption.
