Spanish alphabet
The Spanish alphabet consists of the following 27 letters:It has the 26 letters of the Latin alphabet plus the letter Ñ, representing a voiced, nasal palatal sound. Since Ñ is a separate letter, and not an accented character, it is alphabetized after N. So, in English piñata comes before ping-pong (accented n), but in Spanish it's the other way around (separate letter).
There are three sounds in the Spanish language which are represented by digraphs, namely ch, ll and rr. Traditionally ch and ll were alphabetized after c and l respectively. In 1994 the Spanish Academy dropped this custom joining other dictionary makers. The reasons for this were because it makes alphabetization too different from other European languages and it was difficult to understand by humans. It also can be noted that it is linguistically incorrect to identify graphss with sounds.
Apart from this, acute accents indicate stress (á, é, í, ó, ú). Also "ü" is used in sylables güe and güi to indicate that the u is pronounced, as it would ordinarily be silent in gue and gui, and ge, gi represent a different sound.
