The phrase "haddest change of heart" may seem confusing in terms of its spelling, but it makes sense once you break it down phonetically. The word "haddest" is pronounced with a short "a" sound followed by a "d" and "t" sound at the end. The "change" component is pronounced with a long "a" sound, followed by the "n" and "j" sounds. Finally, "of heart" is pronounced with a short "o" sound followed by the "f" sound and the "h" sound, then a long "a" sound and "t." Together, these sounds form the phrase "haddest change of heart."
