Etymology: "Heliophilous" is built from two Greek elements: "helios," the sun, and "philos," meaning loving or fond of, which also gives English words like "philanthropy" and "Anglophile." Put together, the literal sense is "sun-loving," and the word applies that idea to plants and animals that thrive in strong light. A plant that grows best in open, sunny ground rather than in shade is heliophilous. The second element, "-philous," is the adjective ending that appears in many scientific terms of this kind, such as "acidophilous" (acid-loving) and "calciphilous" (lime-loving). Botanists and ecologists use this pattern to name a plant's habitat preference in a single word, so the "-philous" ending carries the same meaning across many fields.
