The kanji 枯 (pronounced *kare* or *ko*) primarily conveys the meaning of "wither," "dry up," "wilted," or "dead" as it relates to plants. It describes a state of lifelessness or the loss of vitality, often due to lack of water or the natural process of aging.

The kanji 枯 is a phono-semantic compound (形声文字 *keisei moji*). It is composed of the semantic component 木 (ki/moku, meaning "tree" or "wood") and the phonetic component 古 (ko, meaning "old" or "ancient" and providing the sound). The combination of these two parts suggests a tree that has become old and therefore withered or dried up. The evolution of the character reflects the gradual weakening and loss of vitality in a tree or plant.
