Etymology

Origin of sequoia

An Americanism dating back to 1840–50; named after Sequoya

Explanation

A sequoia is an ancient, towering redwood tree that grows on the coast of northern California and southern Oregon. Sequoias are the largest trees on Earth. Before commercial logging destroyed many of them, giant sequoias covered the entire coast of California, filling about two million acres of forest. The remaining trees are among the very oldest things on our planet; some are more than 2,000 years old. Sequoias are massive evergreens, the largest of which is as tall as a 30-story building. The sequoia was named after the Cherokee man, Sequoya, who invented a written form of the Cherokee language in the 1820s.
