👉 Tails, a term in various languages, refers to something that grows or develops into a particular form or shape over time. In many languages, "tails" are typically associated with growth or development. Definition: The word "tails," derived from the Greek roots "tairei" (to grow) and "taie" (shape), describes a specific type of growth in animal behavior, particularly in animals like birds, where they can transform into different forms by developing. This is often used metaphorically to describe an individual or thing changing gradually over time. Tails are said to be the natural result of a bird's developing wings and feathers that allow it to fly.
