The spelling of the word "most strepitous" might seem confusing at first, but it can be broken down with IPA phonetics: /moʊst/ /ˈstrɛpɪtəs/. The first part, "most", is pronounced as "mohst" with a long 'o' sound. The second part, "strepitous," is pronounced as "strep-uh-tuhs" with a schwa sound in the middle. Together, the two words mean "extremely noisy or loud." While the spelling may be difficult, understanding the pronunciation will help make the word easier to use and understand.
