ROOT-WORD is HELIO which comes from the Greek Helios SUN. From this root we enrich our vocabulary with words from photography, sun worship, the science of the sun, sunbathing, sub-therapy and sunflowers. In Greek Mythology Helios, the Sun-god drove his sub-chariot across the sky every morning. In our day sun-therapy cures rickets, tuberculosis, and is a preventative of many ills. The fragrant heliotrope is a garden favorite, and sunflower seeds are healthful.
