Etymology
Origin of arboreal
First recorded in 1660–70; from Latin arbore(us) “of trees,” equivalent to arbor “tree” + -eus- -eous + -al 1
Explanation
If it has to do with trees, you can call it arboreal. Monkeys that live in trees are arboreal. The rings of a tree are an indication of arboreal age. The word arboreal comes from the Latin arboreus, which means "pertaining to trees." It's a word that refers not just to animals that live in trees, but also to anything that resembles the branching form of a tree — like a chandelier or a family geology drawn out. It even can be used to describe, as its Latin root suggests, something pertaining to trees. A Christmas tree shop is an arboreal wonderland. There are trees everywhere!
