I'd anyone able to describe how to pronounce 'jsi'? From my understanding, all letters are pronounced in Czech, but the way Duolingo pronounces it is with the J silent
Are you sure? I thought that works the same way in every Slavic language, so it could be both "a" and "the", depends on the context. "Ta" wouldn't be necessary. It works that way in Polish and Russian, maybe in Czech it's different, let me know.
