¡Feliz Año Nuevo!
Happy New Year!
When you say Happy New Year in Spanish it's vital to spell it with the ñ.
The ñ pronounced "enye" is a letter in its own right.
To not use the ñ and to use just the letter "n" changes the pronunciation and also can change the meaning of the word.
The word ano without the squiggly line, also known as the tilde, translates politely into the word butthole.
So to say Feliz Ano Nuevo means Happy New Butthole.
So this new year try not to say something embarrassing.
The actor Michael Peña says it best in this skit. The ñ is like an "n" with a moustache.
