arborvitae

the word arborvitae is a direct borrowing from new latin, where it functioned as a noun phrase meaning "tree of life". this name was given by 16th-century french explorers in canada, who learned from indigenous peoples about the medicinal properties of the tree's sap and foliage, which were used to treat scurvy due to their vitamin c content. the term elegantly combines two classical latin words, 'arbor' and 'vita', to describe a tree believed to sustain life. it entered english in the late 17th century as a scientific and common name for these evergreen conifers, preserving the original descriptive logic.

Structure: arbor (tree) + vitae (of life) arbor is a latin noun meaning "tree". vitae is the genitive singular form of the latin noun vita, meaning "life".
