The correct spelling of the word "most prominent" is not "wast prominent". The correct pronunciation of this word is /məʊst ˈprɒmɪnənt/. The "w" in "wast" is incorrect and should be replaced with the correct letter "m". The sound for "m" is represented by the IPA symbol /m/. Double-checking spelling before submission can be helpful to avoid mistakes like this. It's important to maintain proper language standards in any written communication.
