An oracle is a person or thing considered to provide insight, wise counsel or prophetic predictions, most notably including precognition of the future, inspired by deities. If done through occultic means, it is a form of divination. Description. The word oracle comes from the Latin verb ōrāre, "to speak" and properly refers to the priest or priestess uttering the prediction. In extended use, oracle may also refer to the site of the oracle, and the oracular utterances themselves, are called khrēsmoí (χρησμοί) in Greek.
