The spelling of the word "TAHT" is peculiar as it appears to have a silent "h". However, the correct pronunciation of this word is [tæt], where the "h" is not silent but rather pronounced as a glottal stop. In IPA phonetic transcription, the symbol for the glottal stop is represented as [ʔ]. Therefore, "TAHT" should be pronounced as "tæʔt". It is important to note the presence of the glottal stop in certain words, as it significantly changes their pronunciation.
