enchant_dict_store_replacement — Add a correction for a word
Add a correction for 'mis' using 'cor'. Notes that you replaced @mis with @cor, so it's possibly more likely that future occurrences of @mis will be replaced with @cor. So it might bump @cor up in the suggestion list.
The work to fix
The correct word
TRUE in caso di successo,
FALSE in caso di fallimento.
