The Alfabeto Unificado para a Escrita do Caboverdiano (Unified Alphabet for Cape Verdean Writing), commonly known as ALUPEC, is the alphabet that was officially recognized by the Cape Verdean government to write Cape Verdean Creole.
The ALUPEC is a phonetic writing system based on the Latin script and states only which letters should be used to represent each sound. The system does not establish rules for spelling (orthography). For that reason, Cape Verdean creole writing is not standardized; the same word or the same sentence may appear written in different ways. Cape Verdeans, then, write idiosyncratically — that is, each person writes in his or her own dialect, sociolect, and idiolect.
The descriptive texts concerning the ALUPEC claim that it is “a system composed by 23 letters and four digraphs”. What those texts do not specify is that the ALUPEC also includes the letter Y and the digraph RR.
Older documents, such as the 1994 Proposed Criteria of the Unified Alphabet for the Cape Verdean Writing System, showed the following order:
