metrophobia
n. an irrational fear of poetry

Obscure words from Paul Hellweg’s Insomniac’s Dictionary, 1989:

tomecide: the destruction of a book

lampadomancy: augury by torch flame

shotclog: a drinking companion tolerated because he pays for the drinks

allonym: the name of a real person borrowed by an author

ephelides: freckles

feuterer: someone who keeps a dog

hypnopedia: the process of learning while asleep (e.g. by listening to a recording)

girouettism: the practice of frequently altering personal opinions to follow popular trends

panchreston: a broadly inclusive thesis that purports to cover all aspects of its subject but usually ends up as an unacceptable oversimplification

grangousier: one who will swallow anything

A few facetious Latinisms collected by Michael Quinion:

ferroequinologist: a railroad enthusiast (“one who studies the iron horse”)

infracaninophile: a lover of the underdog

anti-fogmatic: an alcoholic drink that counteracts the effects of fog

In 2014 a Futility Closet reader led me to elephantocetomachia, “a fight between an elephant and a whale,” a valuable word assembled from spare parts. And my notes say that vacansopapurosophobia means “fear of blank paper” — a useful expression, even if it’s not in the dictionary.

Doubtful but entertaining:

Several sources define vacansopapurosophobia as “fear of blank paper” — it’s not in the Oxford English Dictionary, but it’s certainly a useful word.

I’ve also seen artiformologicalintactitudinarianisminist, “one who studies 4-5-letter Latin prefixes and suffixes.” I don’t have a source for that; it’s not in the OED either.

In Say It My Way, Willard R. Espy defines a cypripareuniaphile as “one who takes special pleasure in sexual intercourse with prostitutes” and acyanoblepsianite as “one who cannot distinguish the color blue.”

In By the Sword, his history of swordsmen, Richard Cohen defines tsujigiri as “to try out a new sword on a chance passerby.” Apparently that’s a real practice.

And one that is in the OED: mallemaroking is “the boisterous and drunken exchange of hospitality between sailors in extreme northern waters.”

xenodochiophobia
n. fear of (or worry about) hotels

Art historian Bernard Berenson offered this word in his 1952 memoir Rumour and Reflection:

I invented it long ago to designate the sinking feeling that in my travels often overcame me: of fear lest the inn or hotel at which we were to lodge would be sordid, would not let me have the promised apartment; that my bedroom would have the wrong proportions, mulling or flattening me out of my normal shape and squeezing me out of my own way of breathing; that the lights would be glaring and no reading lamp by my bed; that there would be sharp or clattering sounds outside, or bad smells without or within. Motoring in the Vendee or Poitou, in Spain or Greece as evening darkened, tired or even exhausted, I would wish the destination farther and farther away, for fear of what I should find when I reached it.

When William Tazewell mentioned the word in a 1989 travel article in the New York Times, reader Louis Jay Herman wrote to add “a few more suggested contributions to the Hellenizing of the travel language”:

And cacohydrophobia, loosely translatable as Can I drink what comes out of the tap in this joint?

pentheraphobia

n. fear of one’s mother-in-law

Above: “My Wife and My Mother-in-Law,” from Puck, November 1915.

Asked what was the maximum punishment for bigamy, Lord Russell of Killowen said, “Two mothers-in-law.”
