Word Root of conscious

The Latin word scīre, meaning “to know” or “to understand,” gives us the root sci. Words from the Latin scīre have something to do with knowing or understanding. Science is the understanding of the world and how everything in it works. A person's conscience is the knowledge of right and wrong and the feeling that he or she should do right. Anything that is conscious knows what it is feeling.
