What does hoar mean?
Hoar is an uncommon literary word with two closely related uses. As a noun, it denotes frost, particularly the delicate white coating that forms on grass, leaves, roofs, and other exposed surfaces during cold nights. As an adjective, it describes something covered with such frost, and by extension it can describe hair or a beard that is white or gray with age. The word has an old-fashioned, evocative quality that suits poetry and descriptive writing about winter or age. It is also sometimes used as a modifier in the familiar expression “hoar frost,” although “frost” is the ordinary modern term. Although hoar can be understood from context, it is worth knowing because it gives concise and vivid expression to the appearance of wintry landscapes and aged features.
