Homophony avoidance in the grammar: Russian nominal allomorphy

It has long been observed that languages tend to preserve contrast, either by introducing sound changes or by inhibiting them. However, it is not clear if any instances of so-called homophony avoidance reported to date constitute an active synchronic restriction in the grammar. This paper presents an instance of homophony avoidance in Russian masculine nouns. A perception experiment shows that the trends observed in the corpus are only partially extended to nonce words. I argue that the asymmetry observed in the experimental results can only be attributed to a synchronic restriction against homophonous forms in the same paradigm. Thus this paper presents strong evidence in favour of a synchronic anti-homophony constraint.
