The phrase "gliding by" implies a smooth and effortless movement. Its antonyms, on the other hand, convey the opposite meaning. Words such as crashing, stumbling, tripping, stumbling, and tumbling suggest awkwardness and lack of grace, as if the person or object is struggling to move or stay upright. Other antonyms include lurching and jerking, which describe movements that are sudden and uneven. These antonyms remind us that movement is not always smooth and effortless, and that sometimes we need to work hard to overcome obstacles and challenges.
