The correct spelling of the word "rison" is actually "reason". The /i/ sound is spelled with the letter E-A together, and the /s/ sound is spelled with the letter S, not the letter N. The IPA phonetic transcription for "reason" is /ˈriːzn/, with the stress on the first syllable. It is important to pay attention to spelling and pronunciation, as clarity in communication is crucial in any language.
