Etymology: "Macrophyte" is a technical coinage built from two Greek elements: "makros," meaning "large," and "phyton," meaning "plant." The compound was formed in German as "Makrophyt," and English took it from there. Its first element is the same "macro-" seen in words like "macroeconomics" or "macroscopic," where the sense is "on a large scale" rather than "big" in any casual way. The second element, "-phyte," is the common scientific suffix for a plant, found in words such as "epiphyte," a plant that grows on another plant, and "saprophyte," one that feeds on dead organic matter. Scientists assembled this kind of Greek-based vocabulary in the 19th and early 20th centuries to name groups of organisms, so the word is a modern label rather than an ancient one. In practice, the term separates the large plants of ponds, lakes and streams from the microscopic algae that also live in water. Ecologists use it to refer to these visible aquatic plants as a group, and the name reflects that distinction in size.
