"In satiate" is spelled with the letter "i" before "n," not "e." This is because the prefix "in-" is followed by the vowel sound /ə/ (schwa), which is represented by the letter "i" in this case. The final "-ate" is pronounced /eɪt/ and represents a verb form indicating the act of satisfying or filling completely. To properly spell and pronounce this word, it is important to understand the role of each letter and sound within it.
