There is only one 15 letter word which doesn't repeat a letter. What is it?

"complementarity" - this word uses 'm','e', and 't' twice but not next to each other. If that's what you meant by repeat, then, I've got 35 other 15 letter words like it. If you meant doesn't reuse any letter, then I found none in my Unix dictionary (/usr/dict/words).

I mean no repeat of any letter anywhere in the word so it's wrong. Where do you find this all out anyway (I'm talking about the 15 other words) etc.

This is just annoying.

That's 4 words Pandora. Wrong

I don't like this survey.

mandy, that's the first comment in a long while that's made me laugh out loud! Thank you!

Just for you, Pandy :) Just for you!!!!

anon - The Unix operating system has a word list in it, located at /usr/dict/words (not all versions of Unix have this). Anyway, I can use various Unix commands to find words that match a pattern (like "have 15 letters") then run some other checks like that look for repeated letters using something more powerful like perl (another utility). It didn't work though. That dictionary isn't the most complete one around. I found a few 13 letter words:
ambidextrous
bluestocking
exclusionary
incomputable
lexicography
loudspeaking
malnourished

So, what's the answer?

uncopyrightable

"qwiuehrjomslazy" ...I just invented it.

jen - LOL I'm not amused at your misfortune...just your description!

uncopyrightable

I don't know.

There are actually 2 15 letter words that don't repeat any letters.

dermatoglyphics,
and uncopywritable

the 3rd one is misconjugatedly and if you're wondering, there is the 17 lettered: subdermatoglyphic.

Beer

I have no idea.

I don't know. It could be "dermatoglyphics" or it might be "uncopyrightable". I suppose it really depends which one you are looking for and/or which one isn't really a word.
