Right. Review time. Vowel harmony is completely simple to create due to wildcards and the fact that each rule is repeatedly applied until it no longer affects the word. See the following two rules, which handle it for Thagojian: V[+front]*V[+back] > V[+front]*V[+mid] V[+back]*V[+front] > V[+back]*V[+mid] It's phonetic-featural rather than graphemic, and there is a single glyph<-

example) "c" could mean entirely different things in the input and output languages. The symbol inventory is strictly single-character, as is the category inventory. Several SAMPA characters are reserved symbols within the rules definition language, meaning you can't use them as symbols or categories. My workaround to the "input symbol definition == output symbol definition" was to have read rules, process rules and write rules, like PHONO, but that failed. It's DOS, so therefore relies on DOS codepages rather than Windows ANSI, so accented characters get garbled. I think that, despite the enormous raw power of ETYMO, I might have to go back to PHONO, at least until I can port ETYMO to a Unicode-aware Windows application for. As if that day will ever come *sigh* Paul
