Today's words

caduceus \kuh-DOO-see-us\ - 1. the symbolic staff of a herald; specifically : a representation of a staff with two entwined snakes and two wings at the top  2. an insignia bearing a caduceus and symbolizing a physician

Seems as if I should have known this one.  But when I see it, my brain wants to think "adjective" instead of noun," as if it ended in -ous.

And from today's word game:

anadem \A-nuh-,dem\ - (archaic) a wreath for the head : garland

aerolite \AIR-uh-,lite\ - a stony meteorite

screed \SKREED\ - 1a : a lengthy discourse  b. an informal piece of writing (as a personal letter) C. a ranting piece of writing  2. a strip (as of a plaster of the thickness planned for the coat) laid on as a guide  3. a leveling device drawn over freshly poured concrete

I knew the third definition of this last one, and had at least heard the first two before.
