For goodness sake!! It is quite obvious that you are all missing the point of the English language!! Maybe you should all take a crash course and start at the very beginning! Vowels are A, E, I, O, U we have only EVER had 5 vowels... so stop adding to them.

Everyone in England loves the 5 we have!!
Please stop adding Welsh words as Welsh is a different language. The original question was "The longest ENGLISH word without vowels"
