The spelling of the word "INSTANTAN" may confuse some non-native speakers of English. In IPA phonetic transcription, it is spelled /ɪnˈstæntən/, which means that it contains the vowel sound "i" as in "bit" followed by the consonant cluster "st" as in "star", then the vowel sound "a" as in "cat", and ends with the suffix "-an". The word "instantaneous" is a more commonly used alternative, which is easier to spell and pronounce for non-native speakers.
