The phrase "in tending" means to look after or care for something or someone. Its antonyms are the words "neglecting" and "ignoring," which both mean to pay little or no attention to someone or something. When someone is "neglecting" something, they are failing to give it the necessary care or attention, and when someone is "ignoring" something, they are deliberately avoiding it or not acknowledging its existence. While "in tending" represents an act of responsibility and care, "neglecting" and "ignoring" signify apathy and indifference. Hence, it is important to use these words correctly to convey the intended meaning accurately.
