English Is My First Language

"ch" is not a letter just because it's a digraph (nor is "ll")

or accentuated characters (ñ).

Or else the portuguese alphabet would be HUGE.

I dunno about you but that was how the spanish alphabet was taught to me by my family and in high school. :c

ñ is quite an odd case, as other accentuated characters in spanish aren't included in the alphabet because they don't count. At least in Spanish, accents are only there to help you pronounce the word, but ñ make a different sound altogether (sort of).
