👉 Notacanthous is a term used in the field of linguistics and computational linguistics, specifically to describe languages where a word or phrase has no equivalent or alternative form in that language. This can occur due to differences in grammar rules, phonology, or morphology (the study of how sounds are combined into words). Notacanthous languages often have unique grammatical structures or specialized vocabulary that make them difficult to learn and use interchangeably with native speakers.
