Etymology: "Cotyledonous" is simply the adjective built from "cotyledon" with the English suffix "-ous", meaning "having the qualities of" or "relating to." The base noun "cotyledon" came into English through Latin from Greek "kotylēdōn," a word for a cup-shaped hollow, from "kotylē," meaning a cup or socket. The name fits the seed leaves, which are the first part of the embryo to emerge, and which in many plants are the earliest structures visible when a seed sprouts. Because the adjective is a straightforward combination of an existing noun and a common suffix, its history is essentially that of its base. Its meaning stays close to the noun's, so a cotyledonous plant is one that produces these seed leaves, while a cotyledonous structure is one that shares their form or role.
