Grandiloquent Word of the Day @grandiloquentwords.bsky.social · 07/10/2026
Acnestis [ak-NEES-tis] (n.) - The part of the back that cannot easily be reached to scratch. Used in a sentence: “Ever since our illicit dalliance in the back garden, my acnestis has been afflicted with a most infernal rash of Poison Oak, and Miss Drollup has ceased returning my correspondence.”
A "Grandiloquent Word of the Day" meme for “Acnestis,” defined as the part of the back between the shoulder blades that cannot easily be reached to scratch. The example sentence jokes about an illicit garden dalliance, a poison oak rash, and Miss Drollup ceasing correspondence. At right, an antique illustration shows two draped figures with dotted reference lines marking areas of the back.

Immunologist and educator Dr. Florence Sabin died #OTD in 1953. The first woman to hold a full professorship at Johns Hopkins School of Medicine (where she graduated from in 1900) and the first woman elected to the National Academy of Sciences. #WomenInSTEM
A black-and-white historical photograph of pioneering scientist Dr. Florence Rena Sabin (1871–1953) in her laboratory workspace. Dr. Sabin, with her dark hair gathered back, wears thin, round wire-rimmed spectacles and a light-colored lab coat over a dark shirt. Seated in a dark wooden chair facing right, she pivots her upper body toward the camera with a calm, subtle smile. Her hands rest deliberately on a complex, vintage black microscope positioned on the desk before her. The laboratory setting features a dark wooden desk scattered with loose papers and a stack of documents. Behind her stands a tall wooden filing cabinet with numerous shallow drawers, while a large window to the right floods the scene with natural light, illuminating technical equipment nearby. The composition balances the scientific tools with her prominent, dignified presence, evoking an analytical yet warm and welcoming mood. This portrait highlights her legacy as the first woman elected to the National Academy of Sciences.

Physicist Dr. Ursula Franklin helped invent archaeometry--the application of materials science to analyze archaeological artifacts. She used modern physics tools to date/determine the compositions of ancient metals & ceramics to uncover how ancient peoples lived/worked. Born #OTD 1921. #WomenInSTEM
A charming photograph of Dr. Ursula Franklin (1921–2016), the pioneering Canadian experimental physicist, metallurgist, and humanitarian activist. She is positioned slightly off-center against a minimalist, solid slate-blue backdrop. Captured from the chest up, she looks off-camera to the right with a bright, genuine smile that showcases her warmth and sharp intellect. Her short, styled silver-grey hair frames her face, and she wears thin-framed, amber-toned glasses. She is dressed in a crisp, purple-and-white vertically striped button-down shirt. Around her neck hangs a delicate silver chain supporting a striking teardrop-shaped pendant featuring a vibrant orange-red stone or amber setting. The lighting is soft and even, accentuating the fine lines of a long, accomplished life. The clean, professional composition evokes a mood of joyful wisdom, deep dignity, and enduring historical significance, celebrating a legendary woman in STEM.

I think he may “lac” the authority, perhaps because he is barely monolingual let alone bilingual.

If I had to share just one lesson from my decades of teaching, it's that the best way to learn is by talking to someone who disagrees with you.
