The phrase “In extremis” originates from Latin and can be translated to “in the farthest reaches” or “at the point of death” in English. It is usually used to describe a circumstance or condition that has reached an extreme or critical point, particularly when referring to someone’s health or a dire situation. For example, if someone is “in extremis,” it implies that they are in a very critical or life-threatening condition. Additionally, the phrase can be used more generally to indicate a situation that has become extremely challenging or difficult.
