The word milquetoast is used to describe a meek or timid person.

It originated from the comic strip character Caspar Milquetoast, created by Harold T. Webster in 1924. The character was known for his timidity and refusal to participate in controversial discussions. Some time after the character's debut, the term "milquetoast" began to be used to describe people with similar characteristics.

Caspar's last name is derived from "milk toast," a breakfast food that was thought to be easy to digest and was a popular food for convalescents in New England (USA) in the 19th and early 20th century.

A neologism is a newly coined word or expression.

Orthosomnia is an obsession with getting "perfect" sleep. The word was coined in a 2017 article in the Journal of Clinical Sleep Medicine titled Orthosomnia: Are Some Patients Taking the Quantified Self Too Far?

We termed this condition “orthosomnia,” with “ortho” meaning straight or correct, and “somnia” meaning sleep, because patients are preoccupied or concerned with improving or perfecting their wearable sleep data. We chose this term because the perfectionist quest to achieve perfect sleep is similar to the unhealthy preoccupation with healthy eating, termed orthorexia.

I first encountered this term while listening to an episode of The Guardian's Science Weekly podcast called Is sleep perfectionism making us more exhausted?

Phononics is the study of the behavior and control of mechanical vibrations and acoustic waves in materials.

The word is derived from phonon (a quantum of vibrational energy in a crystal lattice, analogous to a photon in light). It seems to be a relatively new neologism, as it doesn't have an entry in conventional dictionaries.

I first came upon this word in a Science magazine article titled Does the mantis shrimp pack a phononic shield?. The study provides experimental proof that the mantis shrimp’s club acts like a biological shock absorber, using phononic filtering to prevent damage.

I learned, from sort of an unlikely source -- the National Park Service, the reason why "night vision" is reset after exposure to light.  That our pupils dilate  is probably obvious, but what I didn't know was that the body produces a protein called rhodopsin which, through a series of chemical reactions, gives our rods the ability to "see" in dim light.  The protein decays in bright light (though much slower in longer wavelengths, i.e. red light).  When depleted, it takes ~30m to regenerate.

Sanewashing (also sometimes hyphened as sane-washing) is a term that rose in popularity during the 2024 US Presidential election to describe the practice of minimizing or explaining some of the bizarre rhetoric from Donald Trump (this is often tied to a critique of "the media").

According to Wikipedia, it originated on a Reddit forum in 2020.

The sentiment that the media has been sanewashing Donald Trump and his campaign perhaps shifted a little with the coverage of Trump’s rally at Madison Square Garden on 27 October 2024. The headline from a NYT article covering the event read Trump at the Garden: A Closing Carnival of Grievances, Misogyny and Racism.

A sawbuck is slang for a $10 bill. Likewise, a double-sawbuck is a $20 bill.

It has been suggested that the slang originated because a sawbuck (sawhorse) resembles an "X," the Roman numeral for "10."

I came across this slang while watching For All Mankind, S3E2.

Something that is specious is superficially plausible, but actually wrong.

You know how there are some words that you know would fit exactly what you're trying to communicate, but you can never remember them? This is one of those words for me.

The Latin speciosus means "beautiful" (or "plausible"). According to Merriam-Webster, in Middle English the word specious was used to mean "attractive." Over time, however, the word was used to denote a fake or superficial beauty.

I don't usually hear this word being used to represent a false-beauty, but more in rhetoric. A specious argument is a type of argument that seems to be good at first glance, but is actually fallacious.

A spoonerism is a slip-up in speech in which the person talking transposes the first part of two words. For example, saying "shake a tower" instead of "take a shower." The word is named after Reverend William Archibald Spooner (1844–1930) who, apparently, this happened to often.

I came across this while listening to an episode of The Allusionist which discussed an old puzzle novel called "Cain's Jawbone." Among the many word-based challenges in this puzzle novel are spoonerisms which the player must identify in order to put the pages in the right order.

From Wikipedia:

Stigmergy was first observed in social insects. For example, ants exchange information by laying down pheromones (the trace) on their way back to the nest when they have found food. In that way, they collectively develop a complex network of trails, connecting the nest in an efficient way to various food sources. When ants come out of the nest searching for food, they are stimulated by the pheromone to follow the trail towards the food source. The network of trails functions as a shared external memory for the ant colony.
