Did you know?
Both words come from Latin "luxuria" (excess, lush abundance), but English specialized them over time: LUXURIANT kept the sense of biological abundance and growth exuberance, while LUXURIOUS took the sense of material opulence. In English, the phonetic similarity causes even native speakers to occasionally mix them, and both appear in non-standard usage in formal texts.
