If 'oology' is the study of eggs, and 'cryptozoology' is the study of hidden animals, then the study of hidden eggs would be 'cryptooology'. Three Os in a row, each of which is pronounced.

Strengths: longest English word with one vowel.

Uncopywritables: longest English word with no repeat letters.

Stewardesses: One of Only five words, in common usage, in the English language which is typed solely with the left hand on a standard qwerty keyboard with 12 or more letters.

Bookkeeper: Only word, in common usage, in the English language, which has three consecutive double letters. OOKKEE

Dreamt: Only word, in common usage, in the English language which ends with "mt."

It is often claimed that there is no word that rhymes with "orange". This is untrue. The rhyming word is "doorhinge". I believe I am the only person in the world to have noted this fact.

Does 'door-hinge' really count as a word, though? Plus you've got that h-sound in 'hinge', so the rhyme isn't perfect.

Even if it's a pseudorhyme, it's a pretty damn close pseudorhyme, and will be almost perfect depending on your dialect.

A few more oddities:

"Rhythms" is the longest word in Modern English without vowel letters in common usage. The longest outside of common usage is "symphysy", but it is now considered archaic. If you want to get technical and count "y" as a vowel letter (a few people have), then the longest word with no vowel letters in common usage is "nth" (as in, to the "nth degree"), and the longest outside of common usage is "crwth", a borrowed Welsh word for a violin-type instrument.

Moving into phonetics, rather than orthography, "twelfths" is a rare English word with a four-consonant cluster in the one syllable. In theory, you could improve on this, if twelfths was a verb - "twelfthsed" would be pronounced by most speakers as "twelfthst", thus providing a five-consonant cluster. There is probably not a limit to how many consonants you could attach to the end of a word - the only limit would be word construction rules.

At the beginning of words, however, the longest consonant cluster available is only three, and it's a very restricted set:

[s] + [p/k/t] + [r/l/w]

There are no initial three-consonant clusters that deviate from this rule. And now you know!

If you are so drunk you can only pronounce vowels, does that make you inconsonant?

oOo!

Or to quote the Librarian: OoOk

They'll all come back the next morning during the consonantal brkfst.

I hate the word 'orange'; I abhor it,
Because their is no rhyme for it.
Neither Calvin nor Ange
Can rhyme orange
Because there is no rhyme for it.

(Cal and Ange are friends of mine, and this came to me as we waited for my daughter to be born. As pseudorhymes go, it's pretty heavy on the 'pseudo' but I still like it.)

If any particular day
Could be described by the variable k
Then the next day of the month
Is described as the k+1th
Day that is one day away.

(This one has been fighting to get out this past week since I heard the phrase 'k+1th', so there you go fresh and new.)

Why cryptozoology?
Why not zooology? The study of animal eggs. Or it might even be zoooology!
I don't see why you bother to bring the crypto- in when you have a perfectly good zoo-.

Maybe it's just me.

Because the "zoo-" has a different "o" sound from the "oology". "New" verses "Wall". You also don't pronounce one of the "o"s in "zoo-"

Plus: Mystery Eggs. It's so much cooler.

It would sound like this: zoo-uw-ohl-ogy. Three o sounds.

Yup just you and anybody who ever played through the Singing Pirates section of the "Curse of Monkey Island" computer game.

Although the pirates in question seem less than satisfied with the rhyme.

I tell you, when I encountered the singing pirates part of CoMI for the first time, my face broke into the biggest grin...

We'll fight you in the harbor.
We'll battle you on land.
But when you meet singing pirates...
They'll be more than you can stand.

"Ooooh! That was a good one!" "No, it wasn't."

(For the uninitiated...)
