The correct spelling of the phrase "argues in to" is often mistakenly written as "argues into." While both versions are commonly used, the former is the correct spelling as "in to" denotes entering or moving towards an inside space. To simplify the pronunciation, "in" is pronounced as "ɪn" and "to" as "tu." So the phonetic transcription of this phrase would be "/ˈɑːɡjuːz ɪn tu:/." It's important to practice proper spelling to avoid miscommunication and confusion.
