It is an adjective of a dusky yellowish-green color; olive green.

This word originated from the Latin word “olīvāceus,” from a combination of the words “olīv(a)” (olive) and “aceous” (the nature of).

Olivaceous describes an olive green, deeper than grass green. Olive trees are native to Asia Minor, but have spread throughout the Middle East and the Mediterranean. This evergreen is the world’s oldest-known cultivated tree, known for being grown by farmers before the onset of written language.
