Elucidate comes from Late Latin elucidare, to clear up, from ex-, e-, out of + lucidus, bright, from lux, luc- light. Hence to elucidate is to bring the inner light out of an obscure subject. One who elucidates is an elucidator; that which tends to elucidate is elucidative; the act of elucidating, or that which elucidates, is an elucidation.
