Meddling is the act of interfering or meddling in someone else's affairs without their permission. However, the term is quite negative, and it is important to have synonyms that can convey the same meaning in a more positive or neutral manner. For instance, the word "intervening" can be used to describe a situation where someone interferes with something for a greater good or altruistic purpose. Other synonyms for meddling include "prying," "intruding," "interfering," "butting in," and "interceding." Depending on the context, these synonyms could be more applicable in certain settings. All in all, using the right synonym can help describe the behavior more accurately and without offending anybody.
