title_body: Use of string reversion in conlangs I came across the Esperantido Universal where reversion of stems (e.g., mega "big" ⁒ gema "small", -a is the adjective ending) is used to denote antonymy. Are there other conlangs using this unusual and un-naturalistic device?
upvoted_answer: Solresol actually reverses the syllable order of a word to denote an opposite meaning, though this occurrence is inconsistent through the creator's published dictionary. For example, fala means good, but lafa means bad, and falaredo means accessible, but dorelafa means inaccessible.
