The correct spelling of the word "most waving" is likely "most-waving." The hyphen is used to indicate that "most" is modifying the compound word "waving." In IPA phonetic transcription, this word would be pronounced as /moʊstˈweɪvɪŋ/. The stress falls on the first syllable of each word, and the "v" sound is pronounced as /w/, as is common in English. Spelling can often be tricky, but paying attention to such details can help convey your intended meaning accurately.
