And A -Z.
"When ‘&’ was the 27th letter of alphabet i.e. X, Y, Z and ‘&’, the school children used to recite the alphabets as X, Y, Z and per se and. “Per se” means by itself, essentially it becomes X, Y, Z and by itself and. So the word “ampersand” is formed by the wrong pronunciation of “and-per-se-and”. Such words are called mondegreen."
