Ok, I will... but I don't think it's possible to find such a word when you don't know it... it'll be damn hard to conclude a word like that I'd say...

It's a bit difficult, and I still haven't had time to find it. Give it a couple of days in case someone else knows it.

2nd hint: all the five vowels occur...

What's the longest possible English word in that every letter occurs only once?

hehe, A scan of my database (for a word game we're doing) got: ethylenediaminetetraacetates at 28 letters But I don't think chemical names are counted right? This was the query for anyone interested: SELECT MAX(LEN(EN)) AS ml, EN

holophrastic (adjective) and to make up for yesterday.... how about..... scuttlebutt By the way. does anybody know what the longest word in the English dictionary is?
