In the current state, the plugin would rename "Classes" to "Classe" when converting from plural to singular. Clearly classe is not a proper word.
To fix this it's quite simple. Simply check if the word ends with "sses". If yes, remove "es". This would properly rename words like "glasses", "passes", "classes", "masses", etc, while words like "vases", "houses" are still properly renamed, since they end in "ses", not "sses".
