much space to justify the phonetic value of the signs they used, but neither was completely successful in clearing the doubts of interpretation of these symbols. In fact their interpretations differ markedly, casting doubt on some sounds. Lehman made a useful comparison of existing sources, enriched with observations of 1929. The long-awaited field notes of Brüning from 1904 to 1905 have been kept in the Museum of Ethnology, Hamburg, though still unpublished. An additional complication in spellings interpretation of different scholars is the fact that between the 16th and the 19th century the language experienced a remarkable phonological change that make even more risky to use the latest data to understand older material. Vowels The language probably had six simple vowels and six more elongated vowels: /i, iː, ä, äː, e, eː, ø, øː, o, oː, u, uː/. Carrera Daza and Middendorf gave mismatched systems that can be put in approximate correspondence: Morphology Some suffixes in Mochica as reconstituted by Hovdhaugen (2004): sequential suffix: -top purpose suffix: -næm gerund suffixes: -læc and -ssæc gerund suffix: -(æ)zcæf gerund suffix: -(æ)d Lexicon Some examples of lexical items in Mochica from Hovdhaugen (2004): Nouns Possessed and non-possessed nouns in Mochica: Locative forms of Mochica nouns: Quantifiers Quantifiers in Mochica: Numerals Mochica numerals: Surviving records The only surviving song in the language is a single tonada, Tonada del Chimo, preserved in the Codex Martínez Compañón among many watercolours illustrating the life of Chimú people during the 18th century: Ja ya llunch, ja ya lloch In poc cha tanmuisle pecan muisle pecan e necam Ja ya llunch, ja ya lloch Emenspochifama le qui ten que consmuifle Cuerpo lens emens locunmunom chi perdonar moitin ha Ja ya llunch, ja ya lloch Chondocolo mechecje su chrifto po que si ta malli muis le Mey po lem lo quees aoscho perdonar Mie ñe fe che tas Ja ya llunch, ja ya lloch Quingnam, possibly the same as Lengua (Yunga) Pescadora, is sometimes taken to be a dialect, but a list of numerals discovered in 2010 which is suspected to be Quingnam or Pescadora is not Mochica. Learning program The Gestión de Cultura of Morrope in Peru has launched a program to learn this language, in order to preserve the ancient cultural heritage in the area. This program has been well received by people and adopted by many schools, and also have launched other activities such as the development
