Puzzle of the Day

Tom was trapped in the can on the left; luckily, he got out. Which Proofniks are still trapped in the other jars/bottles? (Somebody help!)

                              

Check back tomorrow for the answer, a shoutout to all the solvers, and a new puzzle!

Previous puzzle:

What is the longest English word you can think of that has only one distinct vowel in it? As an example, PROOFSCHOOL would be a great submission... if it were one word.

I'll recognize the best entry/entries for each vowel tomorrow. (You can submit more than one.) No dictionaries or computer assistance allowed, and here's a pro tip: Y is a vowel when it makes a vowelly sound.

Answer:

Well, this was a great way to crowdsource a collection of words that are fun to say. I've listed all the submitted words below.

Questions were raised about what counts as an English word. The green words are the orthodox winners (hey, "orthodox" would have been a good submission!); they're the longest submitted words that are noncapitalized and appear widely in dictionaries. But the pink words are the winners if you believe in them. 😊

A: Alabama⁷ (why not Arkansas?), anagrams⁸, abracadabra¹¹ (Mr. Gregg), tattarrattat¹² (Leo and Jessica; coined by James Joyce!)
E: Electrek⁸, beekeeper⁹, deserters⁹, resentences¹¹, represented¹¹, strengthened¹², shepherdesses¹³, relentlessness¹⁴, and strengthlessnesses¹⁸ (whoa Maddy)
I: lightning⁹, crippling⁹, inflicting¹⁰, gimmicking¹⁰, stipplings¹⁰, Mississippi¹¹ (Atticus, Mr. Gregg) and sprinklings¹¹ (Atticus)
O: poolroom⁸, composts⁸, confronts⁹, tomorrows⁹, clockworks¹⁰ (Anna K.)
U: ubuntu⁶ (which is this, but also this), unjust⁶, untruthful¹⁰ (Jessica)
Y: syzygy⁶, rhythms⁷ (Jessica), and twyndyllyngs¹² (Leo; Wiktionary thinks it's real though the OED doesn't)

I'm dumbstruck. Such effervescence! Now I could go for some taramasalata.
