General terms:
* Peninsula: A large piece of land extending into a body of water, with a narrow neck connecting it to the mainland.
* Island: A piece of land completely surrounded by water. However, a piece of land almost surrounded by water could be considered an island if the connecting land is very narrow or insignificant.
* Promontory: A high point of land that extends into the sea, often with a steep cliff face.
* Headland: Similar to a promontory, but often smaller and less steep.
Specific terms:
* Cape: A point of land jutting out into the sea, often marked by a change in coastline.
* Spit: A narrow strip of land extending from the coast, often formed by deposited sediment.
* Isthmus: A narrow strip of land connecting two larger landmasses, often with water on either side.
The best term to use will depend on the specific characteristics of the piece of land. For example, a large piece of land with a narrow neck connecting it to the mainland would be considered a peninsula. However, a small piece of land with a very narrow connecting strip might be considered an island.
