The spelling of the word "IENT" may seem confusing, but it actually follows the rules of English phonetics. The letters "I" and "E" are pronounced as a diphthong, or combination of two vowel sounds, in this case, /aɪ/ and /ɛ/. The letter "N" is a simple consonant sound, pronounced as /n/. Therefore, the correct pronunciation of "IENT" is /aɪɛnt/. Remembering the phonetic sounds of the letters can help avoid mispronunciation and confusion.
