The word "dis-interestedly" refers to the lack of interest or involvement in something. Its antonyms, on the other hand, include "enthusiastically," "passionately," and "eagerly," which indicate an active interest or involvement in a given situation or activity. "Intensely," "ardently," and "keenly" are other antonyms that indicate deep involvement or concern, whereas "interestedly" and "curiously" indicate a general or casual interest. By contrast, "indifferently," "apathetically," and "uninterestedly" are other antonyms for "dis-interestedly" that indicate a lack of interest or concern, suggesting a disengaged or passive attitude towards the subject matter.
