A grove is a group of trees growing together, often in a cluster or small forest-like setting. Synonyms for grove include thicket, copse, woodland, timberland, and forest. A thicket is a dense cluster of bushes and small trees, often impenetrable. A copse is also a small group of trees growing together, but usually with less density than a thicket or grove. Woodland refers to a larger area containing many trees, but not quite a forest. Timberland is a vast area of trees grown for lumber and is often more structured than a grove. Lastly, a forest is a large area of trees, often spanning for miles.
