Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch

Not a word for people who like me don't enjoy same-finger polygrams (in this case, a same-letter tetragram)! :)

I first learnt about it from the Guiness Book of Records. There's also the Swedish 'spårvagnsaktiebolagsskensmutsskutarepersonalbeklädningsmagasinsförrådsförvaltaren' which probably strikes you as alien but I can assure you it's a real word.

On Wikipedia, I also found an article with other nice place names. The New Zealand one dwarfs even the Welsh:

Taumatawhakatangihangakoauauotamateapokaiwhenuakitanatahu

It leads to high hand alternation on Colemak. ;)

Also, a list of long English words with many delightful entries including 'supercalifragilisticexpialidocious'. There's also your beloved 'honorificabilitudinitatibus'! ;)

Oh, and I do love the words 'abstemiously' and 'facetiously'; I'm sure you know why.

For those who didn't get it: The reason I love those two words is that they list the English vowels in correct order. I had to whoop with delight when I heard this.

Oh, here's another good one: Sesquipedalism. A long word describing the love for long words, it's literal meaning being 'foot-and-a-half'! How precious.

That Swedish word up there is a profession: The keeper of the wardrobe of the rail cleaners of the railway stock company! Interestingly, it lists the components in nearly the reverse order as my English translation.
