The word "arenous" is not a commonly used term, but its spelling can be explained using the International Phonetic Alphabet (IPA). The first syllable is pronounced as "a" (æ), which is a short vowel sound produced with an open mouth. The second syllable is pronounced as "re" (ɹiː), which is a long vowel sound produced with the tongue slightly raised towards the roof of the mouth. The final syllable is pronounced as "nous" (nuːs), with a long "u" sound and a soft "s" sound at the end. The correct spelling is "arenous".
