Koreahalvön

Koreahalvön is a name given to several islets and reefs located off the coast of Korea and the surrounding islands. The name, which translates to "Korean half-island", is thought to be related to the Tongyeong islet's unique shape, resembling a half-island.

The term is often associated with several clusters of islands, islets, and reefs located off the southern coast of Korea, including the islands of Shomyoji Chijo, Langtian Namlatosha Shomyoji Chijo, and Samseotang, among others. These islands are located near the city of Tongyeong and are characterized by a mixture of volcanic and limestone outcrops.

The term "Koreahalvön" is an historical name and does not specifically refer to a single fully enclosed area with water connecting it to the mainland. Instead, it seems to describe various small islets and reefs that form a larger archipelago scattered in the sea.

The linguistic origin of the name is unclear, and its meaning has been the subject of debate among linguistics experts. Some believe it could be an archaic verb or noun root while others think it is of very old Korean origins.
