or pejorative? To spell it wrong once is a typo, to spell it twice a mis-spellling. And I'm not being disputatious, nor am I Dixie, although I do punctuate well when I want to.
My dictionary says "expressing contempt or disapproval". and has been used by a very popular poster here. If you are going to use big words, make sure you spell them properly. Although I must say I love the person who made the error.
The single 'L' in the above ^ added to the triple 'L' in the OP now, indeed, means that you have used the correct number of 'L's' for the word 'mis-spelled' (which is actually more commonly spelt 'misspelled')..........
