Definition
快 (kuài) is the everyday word for 'fast, quick' as an adjective, and 'soon, almost' as an adverb. Unlike 快速 (kuài sù, high-speed) which is more formal and often used in written/technical contexts, 快 is used in both speech and writing. 迅速 (xùn sù, rapid) emphasizes swiftness of action, while 快捷 (kuài jié, quick and efficient) is rarer and often describes procedures or shortcuts.
