The correct spelling of the phrase "wast member" is actually "waist member". The IPA phonetic transcription for this phrase would be /weɪst ˈmɛmbər/. The first syllable, "waist", is spelled with the "ai" diphthong and pronounced with a long "a" sound. The second syllable, "member", is spelled as expected, but the "m" and "b" sounds are also closely connected, creating a blend. Together, these two syllables form "waist member", a term that refers to a specific part of a structure or building.
