Sanskrit ruc (40)
According to Monier-Williams’ A Sanskrit-English Dictionary, Sanskrit word ruc refers to “shine, be bright or radiant, or resplendent; to make bright or resplendent; to be splendid or beautiful or good; to be agreeable to, please; to be pleased with; to be desirous of, long for; to enlighten, illuminate; to make pleasant or beautiful.” The word ruc is derived from the root rocate, meaning “to shine, be bright, radiant, or resplendent.” It is linguistically related to Greek λευκός (lefkós), ἀμϕιλύκη (amfilýki); Latin lux, luceo, luna, lumen; Gothic liuhath, lauhmuni; German lioht, lieht, licht; Old English leóht; and English light. It traces its origin to the Tamil root el through the transformation of el > er > ru > ruc. The following words, related to Sanskrit ruc, also originate from Tamil el.
