Pig Latin Translator

Pig Latin moves everything before the first vowel to the end of the word and adds ay, so pig becomes igpay and latin becomes atinlay. This translator applies the common convention for the awkward cases: a word that already starts with a vowel takes way instead (apple → appleway), and a word with no vowel at all just gets ay (nth → nthay). Capitalisation is carried over — an initial capital stays initial, and a word written entirely in capitals comes out in capitals, so NASA becomes ASANAY.

The interesting rule is y, which counts as a vowel everywhere except the first letter. That is what makes yellow come out as ellowyay rather than yellowway, and it is also why my — where y is the only vowel — becomes ymay. Consonant clusters move as a unit, so strength gives engthstray, school gives oolschay and rhythm gives ythmrhay.

Only runs of A–Z and a–z are touched; everything else is left exactly where it is. That keeps punctuation, digits and line breaks intact, but it also means an apostrophe splits a contraction into two words that are each translated separately: don't comes back as onday'tay. Accented letters are outside the range too, so café becomes afcayé — the é sits out the rotation and ends up detached from its word. Hyphenated words are handled as two: one-off gives oneway-offway.

Worth knowing that the translation is one-way in practice as well as in spirit. ymay could have come from my, and ellowyay from yellow, but nothing in the output records how many letters were moved, so a mechanical reversal has to guess — which is half the fun of a code invented by children.
