The ordered series of letters or graphic signs of a language is known as an alphabet. The word, as such, comes from the late Latin abecedarium, which is derived from the name of the first four letters of the alphabet: a, be, ce and de.
The alphabet is the set of spellings that are used to represent the language that serves as a communication system in different human languages.
Our alphabet, for example, consists of 27 letters: a, b, c, d, e, f, g, h, i, j, k, l, m, n, ñ, o, p, q, r, s, t, u, v, w, x, y, z. In addition, in Spanish there are five digraphs, which are combinations of two letters to which a particular sound is assigned: ch, ll, gu, qu, rr.
In Spanish, only simple letters are considered letters of the alphabet, hence from 2010 the ch and ll digraphs of our alphabet have been excluded.
The alphabet of the Spanish language is based on the Latin alphabet, which in turn was adapted by the Etruscans of the Greek alphabet, with its own variants of course. This alphabet, the Latin, would later be adopted in Western countries, including Spain, cradle of our language.
However, there are also other alphabeticals for communication, such as Braille, used by the blind, or the Morse, which is used for communication by intermittent signals.
