The word "IRRA" is a bit tricky to spell because it has sounds that don't match up with the standard English spelling rules. In IPA (International Phonetic Alphabet), "IRRA" is spelled as /ɪrə/. The first sound, /ɪ/, is the short "i" sound like in "bit." The second sound, /r/, is the rolled "r" sound. Finally, the last sound, /ə/, is the schwa sound which is the unstressed vowel sound in many English words like "sofa." Putting them together, we get the phonetic spelling of "IRRA" as /ɪrə/.
