Incorrect spelling, explanation: the pronunciation of this word nowadays may make us think that writen is how we are supposed to spell however the right form is written. This is because the spelling has remained the same since the ages of Middle English, when written was actually pronounced with double t (notice, that if you try to say the word very slowly, double t may be heard).

Correct spelling, explanation: written is spelled with double t because it used to be pronounced in a way that actually emphasized both t’s. The pronunciation then changed, but the spelling remained. Writen is a wrong form as we still write written just like in Middle English.
