👉 Basinasal is a term used in the field of linguistics and computational linguistics. It refers to an artificial language that uses only the letters 'a', 'b', 'c', 'd', 'e' and 'f'. The goal of using only these five letters is to create a sentence that has no meaning without including any other characters. Basinasal languages are often used as models for natural languages, such as English or Spanish, because they can be easily programmed into computers.
