One of the spelling bee words. Means having a protective plate. Search showed I had posted
about a related word, the "lorica" which was Roman thorax and abdomen armor. It reminded
me of names for turtle's plates - carapace on top, plastron on bottom. Plastron is also
name of fencers protective chest and abdomen protector. Reminds me of horrible accident
at a ballgame. Catcher's protection had bottom angled upwards so that a foul tick made
a billiard.
