NATCH-ruhl/ˈnætʃrəl/

Existing or arising by nature rather than human alteration.

The young tree grows in a natural crack beside the wild spring.

A young green tree has sprouted by itself from a narrow crack in a weathered gray boulder beside a small wild spring. Exposed fine roots follow the rock fissure into soil, with moss and uneven grasses; the water emerges between natural rocks. Sparse scene with no pot, tools, masonry or human landscaping.
Etymology

Natura, literally “birth,” also meant the character and course of things. Natural came to describe what belongs to or results from nature, rather than what people artificially make.
