"Castus" is a Latin word that dates back to ancient Rome. Its etymology can be traced to the Proto-Indo-European root *kes- which means "to cut off" or "to separate". In Latin, the word evolved into "castus", which originally meant "cut off" or "separated". Over time, "castus" took on the meanings of "pure", "chaste", or "morally upright" in the sense of being separated from impurities or wrongdoing. This word also gave rise to related words in Latin, such as "castitas" (chastity) and "incastus" (impure, unchaste).
