Several morphological processes cause consonants to be palatalized. For example, the second-person feminine singular form of verbs in the imperfective and jussive/imperative palatalizes one of the root consonants (if one is palatalizable): {"kft"} 'open', "tǝkäft 'you (m.) open', "tǝkäfč 'you (f.) open'. Dental and velar consonants can be palatalized: "t" → "č", "ṭ" → "č̣", "d" → "ǧ", "s" → "š", "z" → "ž", "k" → "kʸ", "ḳ" → "ḳʸ", "g" → "gʸ", "x" → "xʸ".  "r" palatalizes to "y". In one morphological environment the reverse process takes place. In the imperative/jussive form of one class of verbs, the first consonant in the root is depalatalized if this is possible. For example, the verb meaning 'return' (transitive) has the stem consonants {"žpr"} in other forms, for example, žäpärä-m" 'he returned', but the "ž" is depalatalized to "z" in the imperative zäpǝr" 'return! (m.)'. The relationship among "n", "r", and "l" is complex. At least within verb stems, and may be treated as allophones of a single phoneme. The consonant is realized as at the beginning of the word, when this is a "gemination" environment, and when it ends the penultimate syllable of the word. appears otherwise. Banksira also argues that "k" is an allophone of "x" and "b" an allophone of "β". Chaha is transcribed using the Ge'ez (Ethiopic) writing system. It was originally developed for the now-extinct Ge'ez language, and now serves as the orthography for Amharic and Tigrinya. Although there are still relatively few texts in the language, three novels have appeared in the Chaha dialect (by Sahlä and Gäbräyäsus Haylämaryam). To represent the palatalized consonants not found in Ge'ez, Amharic, or Tigrinya, modified characters were introduced to the script, such as using wedges on the tops.
