During a full solar eclipse you can see the sun’s glowing outer atmosphere, called the corona. In Latin, the term corona means “crown” or “garland.” It’s the source of coronation, as well as the coronary arteries that wreathe the human heart, and coroner, originally an officer of the Crown. Another eclipse-related term, penumbra, comes from Latin for “almost shadow,” and refers to the shadow cast by the earth or moon over an area where a partial eclipse is visible. A related word, umbrage, means “a sense of offense” or “resentment.” This is part of a complete episode.
