Kéregre

Kéregre is a term of Hungarian origin that primarily refers to the outer protective layer of trees. This bark layer varies in texture, color, and thickness depending on the species of tree. It serves crucial functions for the tree's survival, including protection against physical damage, disease, insects, and extreme temperatures. The kéregre also plays a role in water regulation and, in some cases, can be a source of food or nesting material for various organisms.

Beyond its botanical meaning, kéregre can also be used metaphorically in Hungarian to describe a protective or outer layer of something else. This might extend to the surface of geological formations, the crust of the earth, or even, in a more abstract sense, the superficial or outward appearance of a person or situation. The literal and figurative uses both emphasize the concept of an external covering that shields or defines an interior. The study and identification of different types of kéregre are important in forestry, botany, and ecology.
