The word "liling" isn't commonly used, but a potential synonym could be "quibbling." Quibbling refers to arguing or finding fault in a petty or minor way. Another possible synonym is "nitpicking," which highlights the act of criticizing small or unimportant details. These words typically connote a negative connotation, suggesting that the speaker is being overly critical or meddling in insignificant issues. While some may see these behaviors as a nuisance, these tendencies can be helpful in certain contexts - such as detecting errors in crucial documents or ensuring precision in a technical field.
