"scruple" as a verb, meaning "hesitate due to conscience".

I think it's used more often in computer science, but the difference between contiguous and continuous. Continuous means "without end" and contiguous means "without break."

Internecine, meaning "destructive to both sides in a conflict".

Petty bickering like that divorce where they had a judge adjudicate the distribution of their beanie baby collection was internecine.

I like penultimate, next to last.

Ultracrepidarian

An ultracrepidarian—from ultra- ("beyond") and crepidarian ("things related to shoes")—is a person considered to have ignored this advice and to be offering opinions they know nothing about.

The word is derived from a longer Latin phrase and refers to a story from Pliny the Elder

The phrase is recorded in Book 35 of Pliny the Elder's Natural History as ne supra crepidam sutor iudicaret[1] ("Let the cobbler not judge beyond the crepida") and ascribed to the Greek painter Apelles of Kos. Supposedly, Apelles would put new paintings on public display and hide behind them to hear and act on their reception.[2] On one occasion, a shoemaker (Latin sutor) noted that one of the crepides[a] in a painting had the wrong number of straps and was so delighted when he found the error corrected the next day that he started in on criticizing the legs.[2] Indignant, Apelles came from his hiding place and admonished him to confine his opinions to the shoes.[2] Pliny then states that since that time it had become proverbial.[2]

Übermorgen, the german word for overmorrow, is in abundant use in Germany. It's far from obsolete or obscure over here.

I'm currently reading through all of Rex Stout's Nero Wolfe mysteries, and one fun feature is that he almost always includes one or more very obscure words. It's a nice little thing to look out for.

In the one I'm currently reading it's, "peculate," meaning to embezzle or steal money. Others include:

• Plerophory - Fullness, especially of conviction or persuasion
• Apodictically - From apodictic: clearly established or beyond dispute
• Usufruct - The right to enjoy the use and advantages of another's property short of the destruction or waste of its substance
• Acarpous - Not producing fruit; sterile; barren
• Yclept - By the name of
• Eruction - A belch or burp

I had a look to see if I could find a full list but sadly not. However most Wikipedia entries for the individual novels include a section called, "The unfamiliar word," if you want to find more.

Sorry

Autodefenestration is one of my faves. The act of throwing yourself out of a window.

If you’re throwing someone or something out, then it’s just plain defenestration

Vituperative. Means vicious.

Grandiloquent/sesquipedalian. It's what you get when you use everything in this thread ₍^ >ヮ<^₎ .ᐟ.ᐟ

I am now adding overmorrow to my vocabulary. I can't wait to confuse the shit out of people I hate.

Hysteresis, the lag or delay between doing something and it's outcome. See also: hysteretic.

I agree that we should use overmorrow more. Japanese has a similar word and it gets frequent use.

"Philomot" was always pretty charming. "The color of a dead leaf."

Vulgar Argot - a word or phrase that is obsolete or incredibly obscure.

Defenestrate means to throw out of a window.

For example, "Someone should defenestrate Putin."

philalethist, A lover of truth.

My contribution is katzenjammer, which is a word describing a really bad hangover (in the English language). I believe it is used a bit differently in the German language, but don't take my word for it.

Uxorious: devoted to one's wife.
