chryselephantine

[kris-el-uh-fan-tin]

adjective

made of or overlaid with gold and ivory, as certain objects made in ancient Greece.

Explanation

Chryselephantine is based on Ancient Greek chrȳsós, “gold,” and eléphās, “elephant.” Because of its similarity to Biblical Hebrew kharúts, “gold,” chrȳsós may have been borrowed from a Semitic language such as Phoenician. Eléphās may also be of Semitic origin. Chryselephantine was first recorded in English in the 1820s. EXAMPLE OF CHRYSELEPHANTINE USED IN A SENTENCE The chryselephantine statue of Athena glistened in the sunlight streaming through the temple.

pervicacious

[pur-vi-key-shuhs]

adjective

extremely willful; obstinate; stubborn.

Explanation

Pervicacious comes from Latin pervicāx, meaning “stubborn, willful” or, more literally, “tending to conquer completely.” The -vic- element derives from the verb vincere, “to conquer,” which is the source of invincible and victory. The -āx part appears as -acious in many English adjectives, such as audacious and loquacious. Pervicacious was first recorded in English circa 1630. EXAMPLE OF PERVICACIOUS USED IN A SENTENCE When the dog walker wanted to change direction, the pervicacious Yorkie dug her nails into the ground and glared.

lilapsophobia

[li-lap-suh-foh-bee-uh]

noun

an irrational or disproportionate fear of tornadoes or hurricanes.

Explanation

In lilapsophobia, lilaps- comes from Ancient Greek laîlaps, meaning “violent storm.” Though laîlaps is also often translated as “hurricane,” the Mediterranean Sea does not have true hurricanes, which form in the tropics. The -phobia element comes from Ancient Greek phóbos, “panic fear.” Lilapsophobia was first recorded in English in the late 1970s. EXAMPLE OF LILAPSOPHOBIA USED IN A SENTENCE Their lilapsophobia began to fade the moment they learned that the tropical wave had failed to organize into a cyclone.

ipse dixit

[ip-see dik-sit]

noun

an assertion without proof.

Explanation

In Latin, ipse dīxit means “he himself said.” The feminine equivalent, “she herself said,” is ipsa dīxit. The plural versions, both meaning “they themselves said,” are ipsī dīxērunt for a group of men or a mixed-gender group and ipsae dīxērunt for a group of women. Ipse dixit was first recorded in English in the late 15th century. EXAMPLE OF IPSE DIXIT USED IN A SENTENCE The protester claimed that aliens were responsible for recent unexplained events, but these ipse dixits all lacked even a shred of evidence.

quincunx

[kwing-kuhngks]

noun

an arrangement of five objects, as trees, in a square or rectangle, one at each corner and one in the middle.

Explanation

Quincunx literally means “five-twelfths” in Latin and is formed from quīnque, “five,” and uncia, “twelfth.” Quīnque is the source of numerous modern Romance words for “five,” such as French cinq and Spanish cinco. Uncia, meanwhile, is the source of both inch and ounce. Quincunx was first recorded in English in the 1640s. EXAMPLE OF QUINCUNX USED IN A SENTENCE Each area of the park featured four bushes arranged in a square, with a bench in the middle to complete the quincunxes.
