Attacapan is a term used to describe a Native American people who originally resided in the present-day state of Louisiana. This term is also used to refer to the languages spoken by this group of people. However, there are some alternative terms that can be used to describe the Attacapan people or their language. For example, the Choctaw people referred to the Attacapan as the "Acolapissa," while the French referred to them as the "Cannibals" due to their alleged practice of cannibalism. Additionally, the Attacapan language is sometimes referred to as the "Opelousas." Despite these alternative names, the term "Attacapan" remains the most commonly used term to describe this indigenous group.
