Hi everyone! I have a question about the interrogative particle - are there any nterrogative particles existing in Czech languge? I know in Polish, it has "czy", in Russian, it has "ли". But what about in Czech? Can the suffix "-li" be some kind of interrogative particle? eg. Chceš-li kavu? Do you want coffee? I think if Czech has interrogative particles, then I can tell if it is a questioning sentence or declarative sentence in a Czech song(because when we sing a song, speaking intonation couldn't be expressed). Thank you for your answers in advance.
