Indubitably!

It means most certainly, beyond questioning.

And it's fun to say!

Grok

It means to know or understand, like "yeah man I can grok that."

Obstreperous - noisy or difficult to control (as in "the boy is cocky and obstreperous")

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

Avuncular - of or having the qualities of an uncle.

“His avuncular joke was both lazy and sexist”

Salitter is my answer to this one every time.

The silence. The salitter drying from the earth. The mudstained shapes of flooded cities burned to the waterline. At a crossroads a ground set with dolmen stones where the spoken bones of oracles lay moldering. No sound but the wind.

Here, also.

Gormless - Lacking initiative, foolish

Copacetic - correct, orderly, good

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

Propreantepenultimate. Fifth to last.

1. Ultimate
2. Penultimate
3. Antepenultimate
4. Preantepenultimate
5. Propreantepenultimate

Interrobang.

It's this thing: ‽

More people should use the symbol because it looks cool and has a badass name, so for that you need to know what it's called.

Who's with me‽

Sonder (noun): the feeling one has on realizing that every other individual one sees has a life as full and real as one’s own, in which they are the central character and others, including oneself, have secondary or insignificant roles: In a state of sonder, each of us is at once a hero, a supporting cast member, and an extra in overlapping stories.

Duodenum.

Doo-odd-in-umm.

The duodenum is the first section of the small intestine in most higher vertebrates, including mammals

I have a double whammy: Nonplussed.

Bewildered; unsure how to respond or act. Double whammy because it does not mean not-plussed like many people seem to think.

I'd settle for not seeing "should/could/would of" typed out anymore.

callipygous : having shapely buttocks

perambulation is a good one. My morning walk isn't quite grand enough to be called a 'constitutional'; nor scenic and leisurely enough to be called a 'stroll'; nor yet social enough to be called a 'promenade'; 'perambulation' is just the ticket.

Brobdingnagian.

It's a very big word that means very big.

It comes from Gulliver's travels. The Brobdingnagians are giants, 12 times the height of humans. The word isn't limited to that scale, but it's definitely for things that are unusually large compared to us.

It's the literal opposite of Lilliputian, which is from the better known race from "Travels" that are 1/12 our size.

It's my absolute favorite word. Not just because it's a literary reference but it's fun to say. Brob ding nag ian. It just burbles off the tongue like a drunken stream stumbling among the rocks of its bed. And, it's a big word that means big, which is just fun wordplay. Like the phobia of big words, hippopotomonstrosesquippedaliophobia, which was inevitable as soon as the idea of a phobia of big words was conceived.
