Etymology: "Cotyledon" is the older and more interesting half of this word. It comes from Latin "cotyledon", borrowed from Greek "kotylēdōn", which named a plant (probably navelwort or a similar succulent) and was also used for a cup-shaped hollow, from "kotylē", a cup or bowl. The leaf-like seed structure got its name from the way the seed's first leaves are cupped or shaped like a little bowl, a comparison that botanists made because the first leaves look like the hollow of a cup. "Monocotyledonous" is a modern scientific coinage, not an ancient term. It combines "mono-", from Greek "monos" meaning "single" or "alone", with "cotyledon" and the adjectival suffix "-ous". The word describes plants whose seeds produce only one embryonic leaf, in contrast to dicotyledonous plants, which produce two. Its precise dating and first use are not given here, but as a technical formation built from classical roots it belongs to the era of systematic plant classification.
