aorta

[ey-awr-tuh]

noun

the main trunk of the arterial system, conveying blood from the left ventricle of the heart to all of the body except the lungs.

Explanation

Aorta comes by way of Latin from Ancient Greek aortḗ, “the great artery” or, literally, “something hung, carried.” Aortḗ comes from the verb aeírein, “to lift, carry,” which is also the source of meteor and may be related to the Word of the Day arioso. Aorta was first recorded in English in the 1570s. EXAMPLE OF AORTA USED IN A SENTENCE The surgeon replaced the patient’s heart valve so his aorta could function normally again.

gridiron

[grid-ahy-ern]

noun

a football field.

Explanation

Gridiron originally meant “griddle” 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, “iron,” 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

[kar-uh-vel]

noun

a small Spanish or Portuguese sailing vessel of the Middle Ages and later, usually with triangular sails that allowed for tacking upwind.

Explanation

Caravel comes from Portuguese caravela, which is formed from cáravo, a kind of ship. Cáravo comes via Latin from Ancient Greek kárabos, “skiff, crayfish, type of beetle,” which likely shares an origin with scarab. For another potential (if unlikely) connection, compare the Word of the Day carapace. Caravel was first recorded in English in the 1520s. EXAMPLE OF CARAVEL USED IN A SENTENCE The cresting waves broke over the caravel as it left the harbor on a windy day.

nomophobia

[noh-muh-foh-bee-uh]

noun

anxiety caused by being without access to a functioning mobile phone.

Explanation

Nomophobia is an abbreviation of “no mobile phobia,” in which phobia refers to general worrying. While the nomophobia we’re featuring today was first recorded in English in the late 2000s, a different type of nomophobia appeared in English at the turn of the 19th century. The earlier nomophobia comes from Ancient Greek nómos, “law, management,” and means “fear of laws.” EXAMPLE OF NOMOPHOBIA USED IN A SENTENCE With their phones confiscated, the teens soon overcame their nomophobia by going for a walk and talking to each other face-to-face.

lambent

[lam-buhnt]

adjective

running or moving lightly over a surface.

Explanation

Lambent comes from the Latin verb lambere, “to lick, wash.” Despite the similar spelling, there is no connection between Latin lambere and English lamb, bent, or the name Lambert (literally “bright land,” from Germanic). We do know that Latin lambere is related to English lap, “to wash with a light splashing sound” or “to lick up a liquid.” Lambent was first recorded in English in the 1640s. EXAMPLE OF LAMBENT USED IN A SENTENCE The torch produced lambent ripples of warm light along the stone walls.
