C.W. Hooper of Keswick sent this creation to the Strand in August 1901: “It contains all the letters of the alphabet, twenty-six in all. They can be traced with patience. The letter N is the smallest (in the centre), and is the only indistinct one.”

“A Lowlands Holiday Ends in Enjoyable Inactivity,” a poem by Miles Kington:

In Ayrshire hill areas, a cruise, eh, lass?
Inertia, hilarious, accrues, hélas!

In certain British dialects, the two lines sound the same.

An invertible word made of impossible letters, by Basile Morin:

An emphatic assertion by Douglas Hofstadter:

In 1908, after observing that chump in cursive reads largely the same upside down, the Strand asked for similar specimens and received this:

Writing in the New Yorker in 1949, John Davenport documented a rising language he’d observed among his countrymen. He called it Slurvian. “When Slurvians travel abroad, they go to visit farn (or forn) countries to see what the farners do that’s different from the way we Murcans do things. While in farn countries, they refer to themselves as Murcan tersts, and usually say they will be mighty glad to get back to Murca.”

bean. A living creature.
course. A group of singers.
fiscal. Pertaining to the body, as opposed to the spurt.
line. King of the beasts.
myrrh. A looking glass.
plight. Courteous.
sport. To hold up, to bear the weight of.
wreckers. Discs on which music is recorded for phonographs.

Writing in the Saturday Review in 1970, Cleveland Amory noted a similar phenomenon in the national pastime:

The pisher no longer goes inna wineup, but a stresh. The firss pish is stry one, followed by ball one. Then stry two, ball two, ball three — the full cown. The ba–er fouls one inna the stanns an the cown remains aa three an two. Finally he flies deep to the senner feeler who makes a long run anna fine runnen catch up againssa wall, beyonna warneen track.

What do you call a person from Connecticut? Today we’d call them a Connecticuter or a Connecticutian (or, colloquially, a Nutmegger), but in a 1987 address etymologist Allen Walker Read announced that he’d also found these options:

• Connecticotian, used in 1702 by Cotton Mather
• Connecticutensian, used in 1781 by historian Samuel Peters
• Connectican, used in 1942 in a letter to the Baltimore Evening Sun
• Connecticutan, used in 1946 by book reviewer John Cournos
• Connecticutite, used in 1968 by an anonymous reviewer in Playboy

He also found several jocular forms:

• Connecticutie, a pretty girl of Connecticut (used in 1938 by Frank Sullivan of Mrs. Heywood Broun and in 1947 by a journalist about Clare Boothe Luce)
• Connecticanuck, a Connecticut person of French background
• Connectikook, an oddball or eccentric from Connecticut
• Connecticutup, a prankster from Connecticut

“Especially in language, exuberance accounts for much that happens.”

(Allen Walker Read, “Exuberance, a Motivation for Language,” (Word Ways 21:2 [May 1988], 71-74. He gives his documentation in “What Connecticut People Can Call Themselves,” Connecticut Onomastic Review No. 2, 1981, 3­-23. In 1992 he took up the same question regarding “Americans.”)
