sequoia

The word 'sequoia' is a modern creation, coined in 1847 by the Austrian botanist Stephan Endlicher to name a newly classified genus of coniferous trees. He derived it from the name of the Cherokee scholar and inventor Sequoyah (c. 1770–1843), who created the Cherokee syllabary, thereby linking the giant tree to a monumental human achievement. The name was chosen honorifically, not based on linguistic roots describing the tree's characteristics. As a proper name adopted into botanical and then general English, it remains an unanalyzable simplex, its meaning entirely defined by its referent—the majestic redwood tree.

the word is a simplex loanword adopted as a single unit. it is a modern latin genus name.
