👉 In linguistics, a finback is a type of animal that is used to illustrate the concept of "fin" in English. Finbacks are typically found on the sides or tips of certain animals' tails, such as dogs, cats, and horses. They are often used to demonstrate how the tail is held up at different angles for balance and coordination. In this context, a finback would be an example of a word that has been borrowed from English but has been adapted in its meaning.
