simply enter a word in English that you would like to see the Nadsat counterpart too. If the word does not have a Nadsat counterpart it is either that there isn't one or it hasn't been added yet as this is still a WIP. The list of added English words with Nadsat counterparts should be shown.
Anthony Burgess's "A Clockwork Orange" is partially written in a language of his own design called Nadsat. Nadsat is mostly composed of Russian, school boy speak, rhyming slang, German, French, Arabic, and a bit of gypsy. The list I am using is provided on https://soomka.com/nadsat.html .
