The spelling of the word "heeact" is a bit confusing. The IPA phonetic transcription reveals that it's pronounced as /hiːækt/. The "hee" part makes sense, as it represents the long "ee" sound. However, the "a" in the second syllable is pronounced as a short "a" rather than the more common long "a" sound. The "ct" at the end is also not a common spelling, as it's usually spelled with a "ck" or "kt". Overall, the word "heeact" is an unusual and uncommonly spelled word.
