Mistralian orthography is a spelling system for the Occitan language, named after the Provençal poet Frédéric Mistral. Developed in the 19th century, it aimed to standardize Occitan spelling and facilitate its use in literature and education. Mistralian orthography is based on phonetic principles, ensuring a consistent relationship between letters and sounds. This system has been widely adopted and remains the most commonly used spelling convention for Occitan today.
