When we talk about "coming to mind," we usually mean ideas or thoughts that appear spontaneously. However, antonyms for this term suggest that the opposite can also be possible. One such antonym is "forgetting," which means failing to remember something. Another antonym is "forcing," which indicates that the idea or thought is arriving deliberately and intentionally. "Suppressing" is another antonym as it refers to an effort not to think about something. Lastly, "blocking" means that a thought or idea is stopped from emerging in one's consciousness altogether. In summary, the antonyms of "coming to mind" demonstrate that the generation of thoughts and ideas can vary in terms of spontaneity, intention, and effort exerted.
