Sauna is Finnish. We use "bastu".
I think muesli might be German (I've seen the spelling "müsli", signifying it comes from a language with u-umlaut).
Fjord is Norwegian.

EDIT: Yeah, according to Wikipedia, muesli is originally from Switzerland, and the Swiss German spelling is "müesli".

And 'formication' is the creepy feeling of spiders crawling along your skin. Talk about a mood-killer!

And there was me thinking it was just a trampling Cyclops legend from the original Ravnica block:

Truth be told, I already thought before your gracious reply that I was "unnecessarily abrupt" - reads "an ass" - in my reply. I apologize!!

I like your style, what you state above, because it is true.

Do you already know the word serendipity? Or serendipitous?

The first I have a certain hope of pronouncing, more or less, but not too much writing out correctly - the latter most likely fails (epic) on most accounts.

Yet what is there not to love about the word?? See "Prince of Serendip" - a Persian tale I think. :-D

I would say this is eastern equivalent to classic "Deus ex Machina" - a god out of machine - only with a purely positive solution; very good, methinks. If you'd like to comment or post another word you like, I'd be delighted.

Besides learning words that give complex ideas just by themselves. I also like to find words with cool origins. Sympathy derives from Latin and means that you suffer with someone.

We have it in Danish too. Skadefryd - noun, and Skadefro - adjective.

And I thought they were using our Ombudsman? Of course, as closely related as Danish, Swedish and Norwegian are, for some words I guess it's more or less impossible to know which of the three languages it was borrowed from.

Müsli I thought - but I am sure there are village orthographies a plenty in CH! ;-)

Defenestrate is an easy one, as fenestra is "window" in Latin (also see German "fenster"). In that context, it's actually quite straightforward (i.e. you're de-windowing someone).

I'd suggest maybe "reticulation" isn't necessary as a word. Though, no doubt, someone will provide a context in which it's invaluable.

An interesting example of a word from literature which has been incorporated into the actual language itself.

Can anyone come up with more?

One of my favourites is robotics. Granted, it's not significantly sesquipedalian, but I find the origin of the word funny. Isaac Asimov coined it back in 1941 without knowing it. He used it in his robot stories, thinking the word already existed. As it happens, it didn't exist, so he is credited with being the originator of the word.

Edit:
Oh, and chortle and galumphing, both from Lewis Carroll's poem Jabberwocky, are officially recognized words now.

Yes, serendipity is a great word, I like the way it sounds; it's very musical. Another word I like for the same reasons as I like serendipity is crepuscule (kriˈpəsˌkyo͞ol/); it's origin is from Latin, but I don't know much else about it :]

Cyberspace is one, and ICE is another, both popularized by Gibson's "Neuromancer" (though Cyberspace was previously used by Vinge in "True Names"; and ICE is sort of a forced acronym, presumably by those who idolize the work).

ICE meaning network security? I must confess I've never seen it used in the real world, although Wikipedia does list a few real world examples. However, I doubt you will find it in a dictionary (other than in the meaning of frozen water).

I don't know either Finnish or German, so I have no idea how to pronoun those words :] But from what I do know, both the German and Finnish alphabets are phonetically similar in some ways to the English one (though some sounds are different), so I can make some guesses as to the pronunciations.

One thing a friend told me was that the Finnish language doesn't have the sound for "b", so a word like "bacon" translates to pekoni; I think it's interesting how some languages don't have certain sounds :]

But here's an interesting site about the etymology of English language words: http://www.etymonline.com/index.php?allowed_in_frame=0&search=bacon&searchmode=none

I typed in bacon, but you can search for others. I am sure there are sites which compile etymologies for the vocab of other languages.

ignominy = a situation or event that causes you to feel ashamed or embarrassed

opprobrium = Harsh criticism or censure

obloquy = harsh or critical statements about someone

serendipity = pleasant surprise

and yes I use them all of them (not so much in english but in my native language yes :P )
