The word "dedicates oneself to" implies complete commitment and devotion towards a particular goal or objective. Its antonyms include the words "abandon", "neglect", "ignore", "forsake", and "distract". When one abandons a task or goal, they give up on it entirely, whereas neglect denotes carelessness and lack of attention. Ignoring a goal means not giving it the importance it deserves, and forsaking it means abandoning it for something else. Lastly, distraction implies getting sidetracked from the task at hand. Using these antonyms in place of "dedicates oneself to" would change the meaning entirely, indicating a lack of commitment, focus, and resolve.
