Did you know?

To be negligent is to be neglectful. Negligence is an important legal concept; it's usually defined as the failure to use the care that a normally careful person would in a given situation. Negligence is a common claim in lawsuits regarding medical malpractice, auto accidents, and workplace injuries. But you can also be negligent about answering your email, or negligent in the way you dress. (The original garment called a negligee was worn by women who had neglected to get fully dressed.) The legal meanings of negligent and negligence, however, tend to be the ones we most often encounter nowadays.
