This paper provides a novel Optimality Theoretic analysis of the 19th century French secret language Largonji. While Largonji is a reversal game, we show that it is a type not previously described, in which the first onset that is not an /l/ reverses, even if it is not at an edge. Thus, traditional approaches to reversal games, such as cross-anchoring, do not work for Largonji. However, our account does not require direct reference to onsets. Instead, it is based on preservation of moraic structure, combined with alignment of a Largonji-specific prefix. Though suprasegmental faithfulness has been noted previously in language games, the present account implements it in Optimality Theory for the first time. Further, in analyzing the Largonji affix as a prefix that is sometimes realized as an infix, we suggest that Largonji provides additional evidence that language games can reflect cross-linguistic patterns not present in the base language.
