Our language is a living entity and constantly changing, this has become clear after the Royal Spanish Academy recently decided to remove "Ch" and "Ll" from our alphabet. This, apart from causing surprise among the enormous number of Spanish speakers, has caused our alphabet to go from having 29 letters to 27 after this decision.
While this decision may seem arbitrary or even "useless" to a certain number of people, it actually serves a very good reason. You see, these were never "letters," but rather exist under the denomination of "digraphs". These are orthographic signs composed of two letters and have a unique sound. In our language, we have "rr", "gu", and "qu". Now, the "ch" and "ll" are added to these.

How will words with "Ch" and "Ll" be written now according to the RAE?
According to the statement from the Royal Spanish Academy:
"The elimination of the digraphs ch and ll from the inventory of letters in the alphabet does not imply, in any way, that they disappear from the graphic system of Spanish. These double signs will continue to be used as before in the writing of Spanish words: the digraph ch representing the phoneme /ch/ (chico [chíko]) and the digraph ll representing the phoneme /ll/ or, for yeísta speakers, the phoneme /y/ (calle [kálle, káye])."

What is considered new is that in the upcoming educational materials and in schools, the mentioned digraphs will no longer be listed as part of the set of letters that we know as our alphabet. The combinations of those letters do not need to be listed in the alphabet to represent the phonemes.
