It’s pronounced nju mə(ʊ)nəʊˌʌltrəˌmʌɪkrə(ʊ)ˈskɒpɪkˌsɪlɪkəʊvɒlˌkeɪnəʊˌkəʊnɪˈəʊsɪs not that that is any great help but, at 45 letters, it is at the time of writing, the longest word to be found in an English dictionary. As for what it is, it’s a lung disease caused by inhaling dust and ash from volcanoes, so it’s a variant of silicosis and pneumoconiosis. It is said to be a made-up word intended simply to be the longest word in the English language, but it isn’t, that title goes to the chemical name for Titin which is a type of protein.
