Lilliputian. Because any word derived from literature is super cool. Also cuckolded, for the same reason (Shakespeare invented that one).

First ones that came to mind: antediluvian and antebellum. The first I like because it has a great rhythm, rolling off the tongue. The latter I've always liked because it tickles me that a word could be coined to reference something so provincial as the US Civil War.

Lastly, I should say that, because of my theater and literature background, I also want to say "cellar door!"

that's cool:D

Hoodwinked. I think it's a marvellous word. =D

I have no idea what my favourite word is.... I use immense a lot at the moment but it's not my favourite.

I, too, like antebellum, harold. But because it makes me think of bellies, and it reminds me of how fat the US has gotten since the civil war. ;o)

So antebellum, to me, is like "anti-bellies." Back when there was no McDonalds, and smaller bellies, or at least fewer large bellies. :o)

I really like soliloquy simply because of how silly it sounds. Nice bit of alliteration there :P Also the word juxtaposition because I can say it and no one has a clue what I'm on about.

'pondering' - It's just one of those really cool words :)

I don't know why exactly but I really like the word anaphora.
Whilst on the subject of literary techniques, chiasmus is a good one too.
I seem to go for the Greek derivatives...

My favorite word is 'doppelgängers' - because of the ä ^^

Poverty. It sounds weird.

Splendid!

squeegee

ridiculous i dont know why :D

love ,sweet,cool,heart

Quandary- it just sounds awesome
Ponder- as "pondering the myesteries of the universe" xD
Amble- ambling up the street
shan't- I shan't!
git- "You filthy git!" I love British slang :D

And seldom, unbeknown, melancholy, smug, futility, forlorn, aghast, mishap....

How can I choose? I just love words.

Edit: Ohhh, a tirade- I love that word.

"Thank you" and "Amazing".

you

"Lord" esp in british pronunciation and "humiliation".It sounds funny :p

Etch and Slurp! I simply love these two words, don't know why though!

Phalanges. It's a funny word.
Same with 'booty'.

I also like the words 'elegant', 'sapphire', 'ruby' and 'dolphin'.
