Notes: The belief in or practice of the occult is known as occultism, and someone who imbibes in occultism we call an occultist. The adjective is occultic. Since today's word is also an adjective, the adverb is occultly. Since it can be verb as well, it has an action noun, occultation, meaning "concealment".

As an adjective we see and hear it in expressions like this: "If God created the laws of the universe, then they are occult by their nature." Finally, the verb pokes its head up in sentences like this: "Benny tried to occult the damage he had done to the car with insistent denial."

Word History: Today's Good Word came from Latin occultus "concealed, secret" via French occulte. The Latin word comprises an assimilated form of ob "over" + cel-are "to cover, conceal". Ob is how PIE epi/opi "near, at, by" emerged in Latin. It arose in Greek as epi "on(to)", in Lithuanian and Latvian as ap- "around, about", and Russian o(b) "around, about". Celare (where C = [k]) descended from PIE kel'- "to cover, conceal", source also of Sanskrit sarana "umbrella, shelter", Latin cella "small room" and cilium "eyelid", Greek kalia "hut, cottage", Welsh celu "to hide", English hull, Hell, and hold (of a ship), German Hülle "coat, hull, cocoon", Dutch huls "hull, case, sleeve", and Gujarati hala "hull, husk".

I wouldn't touch this discission with a ten-foot pole.

The recent lunar occultation of Mars was visible across most of the USA excluding Alaska. In North America it was visible from points north and west of a line extending from roughly Mazatlan, Mexico to the southern tip of Nova Scotia. Unfortunately that means it was not visible along the Gulf coast and the eastern seaboard of the US. It was of course not visible to those of us living on the west side of the Pacific Ocean
