"Fonksiyonel" is a term derived from the word "function," referring to something that is designed to serve a specific purpose or role effectively. In various fields, such as mathematics, engineering, and design, a functional approach emphasizes practicality and usability over aesthetics. In everyday life, functional items are those that fulfill their intended use efficiently. For example, a kitchen tool that simplifies cooking tasks or a piece of furniture that maximizes space while providing comfort are considered functional. The focus is on how well these items perform their designated functions.
