Jak kięvsosta napiszes posikien

It seems like you're asking for help in writing a sentence in Russian. In Russian, "How do you spell this word?" is "Как это пишется?" (pronounced as "Kak eto pishetsya?"). If you provide the sentence you'd like to write, I'd be happy to help you with the spelling. Feel free to share the sentence, and I'll guide you through writing it correctly in Russian!
