How Do You Spell MOST INFECT?
Pronunciation: [mˈə͡ʊst ɪnfˈɛkt] (IPA) 
The correct spelling of the word "most infect" is "most infectious" /ˌmoʊst ɪnˈfɛkʃəs/. The addition of the suffix "-ious" after "infect" changes the word from a verb to an adjective, meaning tending to spread or cause disease. The phonetic transcription /ɪnˈfɛkʃəs/ denotes the stress on the second syllable and the pronunciation of the "f" sound as an unvoiced labiodental fricative. This proper spelling and pronunciation aid in clear communication and understanding of the intended meaning.
