The word "functional" derives from the Latin functio (performance, execution), which stems from fungi (to perform, execute). The suffix -al (from Latin -alis) turns nouns into adjectives, indicating "relating to." Over time, "functional" evolved to describe anything designed for practical use or efficiency, reflecting its roots in action and performance.
