Definition of the word careless

The word "careless" has its roots in Old English and Germanic languages. The term is derived from the prefix "care-" which means "concern" or "attention," and the suffix "-less" which means "without" or "lacking." Therefore, "careless" literally means "without care" or "lacking attention." In Old English, the word "careles" was used to describe someone who was negligent or inattentive. This sense of the word has remained relatively consistent over time, and today "careless" is often used to describe someone who is reckless, negligent, or thoughtless. It's worth noting that the word "careless" has a similar meaning to the word "negligent," but while "negligent" often implies a disregard for rules or regulations, "careless" can imply a lack of concern for others or oneself.
