The word 怠慢 is formed by combining the character 怠, meaning "neglect" or "idle", which itself derives from "心" (heart) suggesting a negligent attitude, with the character 慢, meaning "slow" or "disrespectful", originating from "忄" (heart) and "曼" (prolonged) to imply dilatoriness or lack of courtesy; together they create a compound meaning to treat with negligence or disrespect, often through inaction or delay.
