‘顺利’ is an adjective meaning 'smooth' or 'successful', describing a process or outcome that proceeds without difficulty, obstacles, or delay. The character 顺 (shùn) means 'in order', 'compliant', or 'following the natural course', while 利 (lì) means 'advantageous', 'profitable', or 'sharp'—together they convey the idea of something unfolding effortlessly and favorably. It’s commonly used for events like travel, exams, meetings, negotiations, or personal milestones.

This word emphasizes ease and positive progression rather than just final success—it implies both lack of trouble and favorable conditions throughout. It often appears in set phrases like 顺利通过 (pass smoothly), 顺利完成 (complete successfully), or 一路顺利 (have a smooth journey). While it can modify verbs (e.g., 顺利进行), it most frequently functions as a predicate adjective or adverbial modifier, especially in spoken and written Chinese alike.
