The spelling of the word "m man" can be confusing due to the repetition of the letter 'm'. However, it is fairly straightforward when broken down into its individual phonetic sounds. The first 'm' is pronounced as the bilabial nasal consonant, [m], and the second 'm' is pronounced as the glottal stop consonant, [ʔ]. This creates a pause or break in the pronunciation, similar to a brief catch in the throat. Therefore, the correct IPA transcription for "m man" is: [mˈmæn].
