Duty /duːti/

Ordinarily, people owe a duty to those around them to use a standard of due care such that a “reasonable person” would use in the same situation.  Someone may owe you a duty because it was established by a law, a contract, their relationship to you, a duty they have volunteered, or through an emergency situation.

Used in a sentence: The semi-truck driver owed a duty to not text and drive.
