guffaw

[guh-faw]

verb

to laugh loudly

Explanation

Guffaw means "to laugh loudly." It's the kind of belly laugh that has no restraints and echoes through a room. The word can be used both as a noun and verb and was likely coined to echo the very sound of that booming laugh. With such joyful origins, it's no surprise that people often say laughter — especially a good guffaw — is the best medicine!

oubliette

[oo-blee-et]

noun

a secret dungeon with an opening only in the ceiling

Explanation

An oubliette is a hidden dungeon reached only through a trapdoor — a place where jailers once locked people away to be forgotten. In fact, the word comes from the French word for "forgetting," a grim clue to a prisoner's prospects. Keep the word handy next time you take a castle tour in Europe.

fusty

[fuhs-tee]

adjective

old-fashioned or out-of-date

Explanation

Fusty describes something that feels old-fashioned or unmistakably out-of-date. The word once referred to wine that had gone bad in its cask, and that unpleasant whiff now lingers figuratively over rules that haven't kept up with the times. When a policy seems frozen in a bygone era, call it fusty and make room for fresh thinking!

proprioception

[proh-pree-uh-sep-shuhn]

noun

awareness of the position of one's body

Explanation

Proprioception is your body's built-in GPS, letting you know exactly where your limbs are without a glance. It's why you can walk upstairs while chatting on your phone or sip your coffee without staring at the cup. Some call it a sixth sense, and if you can close your eyes and touch your nose, you'll know proprioception is doing its job!

hermetic

[hur-met-ik]

adjective

airtight; protected

Explanation

Hermetic means "airtight or protected," referring to everything from a sealed lid to an organization that's closed off from outside influence. The term comes from Hermes Trismegistus, a mythical alchemist. You can appreciate hermetic properties when a tight jar finally gives you that satisfying "pop!"
