Quechua alphabet

The Quechua alphabet (Achahala) is based on the Latin alphabet. It is used to write the Quechuan languages. The Quechua alphabet has been use in Peru since 1975, following the Officialization of Quechua by Decree Law in May 1975 that made Quechua co-equal with Spanish.

History
As far as it's known, there was no writing system in the Andes before the Spaniards' Conquest, so that it seems that Quechua languages were first written in some version of the latin alphabet. Quechua language colonial orthography was an adaptation and of Golden Age Spanish typographic conventions. For example, the 5 Latin vowel characters, well-suited for Spanish 5-vowel phoneme system, were used for writing Quechua vowel sounds in a phonologically hyperdifferentiating manner. On addition, labial–velar approximant phoneme was variably transcribed as. Main points in that evolution were Third Lima Ecclesiastical Council orthography and Diego Gonzalez Holguin orthography. The latter used doubled letters to signal aspirated and ejective segments (such as for ). As much as normalized pastoral Quechua disappeared, new orthographic conventions were taken from Spanish renewed orthography or invented. Within the former group, was usually used for transcribing velar, post-velar or glottal fricative phonemes ; within the latter, Ayacucho department local intellectuals normalized the group  to signal  (pronounced  there). Quechua texts edited by non-Spanish Europeans such as Ernst Middendorf in the late 19th century introduced the use of for uvular consonants, which gained some popularity.

It was in the early 20th century that new holistic orthographical proposals appeared, such as Francisco Chukiwanka and Julián Palacios' 1914 alphabet and Julio C. Tello's 1923 orthography. Innovative proposals crystalized in two alphabetic proposals first appeared in Cuzco city: the La Paz alphabet, and the one proposed by poet Andrés Alencaste (also known as Killku Warak'a). The so-called 'La Paz alphabet' was first proposed by editors of Cuzco journal Tradición (Tradition) in 1950, and later ratified in La Paz by the III Congreso Indigenista Inteamericano (Third Inter-American Pro-Indigenous Congress). It remained the most used Quechua orthography until 1975. On the other hand, although unsuccessful, Killku Warak'a's alphabet is almost identical to the current official alphabet, and was the first to apply a phonemic principle to vowels so that he proposed to use just one letter for each vowel phoneme.

For native words
The number of letters employed in writing Quechua highly depends on the Quechua dialect. However, the following are the core letters generally used:

In Ecuador and Bolivia, however, J(j) is used instead of H(h) because ⟨h⟩ and ⟨ʼ⟩ are used to express aspirated and ejective sounds:

In writing some dialects, the and  variations are distinguished by using the letters ⟨e⟩ and ⟨o⟩, respectively, resulting in the use of five vowel letters instead of three. In some dialects, vowel lengths are distinguished by doubling vowel letters to indicate that a vowel is long:

In yet other dialects, with additional sounds, additional letters are employed:

For loanwords
Quechua employs additional letters to write loanwords, mainly originating from Spanish. In careful speech, the letters may represent a Spanish sound, but generally the Spanish sound is replaced with a native sound.

For phonetic transcription
For phonetic transcription, four additional letters are used:
