adj. relating to or following established rules, customs, or conventions

The word "formal" originates from the Latin formalis, derived from forma ("shape, mold, pattern"). The root form reflects the idea of structured arrangement or outward appearance, while the suffix -al (from Latin -alis) turns it into an adjective. Over time, "formal" evolved to emphasize adherence to prescribed rules or conventions, often contrasting with spontaneity or informality.
