Etymology: Monophyllous is a botanical adjective meaning "having one leaf," built from two Greek elements: "mono-", meaning "single" or "alone," and "-phyllous", from "phyllon", the Greek word for "leaf." The "-phyllous" ending is a common suffix in botanical vocabulary, found in words such as "diphyllous" (two leaves) and "polyphyllous" (many leaves). Botanists coined these descriptive terms from Greek roots to classify plants by the number or arrangement of their leaves, so the word belongs to the scientific vocabulary of plant description rather than to everyday Greek.
