A clearing is an area that's open, with no trees, especially one in the middle of the woods or that's been cleared for planting. A clearing at the edge of the forest is a nice place to build a cabin.
The noun clearing is a good way to describe an open place in the midst of dense growth, like a field or a glade in a forest. Some clearings are created deliberately for cultivating crops or building houses, while others come naturally from fires or droughts. This word first appeared in American English around 1818.
