Aorta comes by way of Latin from Ancient Greek 补辞谤迟岣�, 鈥渢he great artery鈥� or, literally, 鈥渟omething hung, carried.鈥� 础辞谤迟岣� comes from the verb 补别铆谤别颈苍, 鈥渢o lift, carry,鈥� which is also the source of meteor and may be related to the 51吃瓜 of the Day arioso. Aorta was first recorded in English in the 1570s.
EXAMPLE OF AORTA USED IN A SENTENCE

More about gridiron
Gridiron originally meant 鈥済riddle鈥� and evolved to refer to things resembling griddles and, ultimately, to sports fields that prominently feature intersecting lines. The term comes from Middle English gridirne, which became gridiron because of a false association with the unrelated word irne, 鈥渋ron,鈥� perhaps because of the metal rods used in griddles. Gridiron was first recorded in English in the late 13th century.
EXAMPLE OF GRIDIRON USED IN A SENTENCE
The staff worked all morning to clear the gridiron of snow so the game could begin.
caravel
noun
a small Spanish or Portuguese sailing vessel of the Middle Ages and later, usually with triangular sails that allowed for tacking upwind.
More about caravel
Caravel comes from Portuguese caravela, which is formed from 肠谩谤补惫辞, a kind of ship. 颁谩谤补惫辞 comes via Latin from Ancient Greek 办谩谤补产辞蝉, 鈥�skiff, crayfish, type of beetle,鈥� which likely shares an origin with scarab. For another potential (if unlikely) connection, compare the 51吃瓜 of the Day carapace. Caravel was first recorded in English in the 1520s.
