Etymology

Origin of arboretum

1830–40; < Latin arborētum a plantation of trees, equivalent to arbor tree + -ētum suffix denoting place where a given plant grows ( cf. alameda)

Explanation

In even the busiest of cities you can often find an arboretum, a sort of museum for trees, where many different types of trees and shrubs are growing, kept for scientific study and for the enjoyment of the general population. The word arboretum comes from the Latin arbor, "tree," and the suffix -ētum, "place," making the meaning "a place of trees." The concept of the arboretum goes back even further than the word itself, all the way to the ancient pharaohs of Egypt, who raised and studied trees from other lands. The oldest known arboretum in the Western world is the Trsteno Arboretum, in Trsteno, Croatia, which was established in the 15th century.
