Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
multilinguismo » multilinguesuismo, multilingualism, multilingmismo, multilingsismo, multilingismo
multiligues » multilingues, multilingual, multipliquen
{uml}uismo." » {uml}mismo.", {uml}sismo.", {uml}ismo."
{uml}sismos." » {uml}mismos."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: "(((multiling OR multilingue) or multilinguismo) or multiligues)({uml}uismo." or {uml}sismos.")~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "(((multiling OR multilingue) OR multilinguismo) OR multiligues)({uml}uismo." or {uml}sismos.")*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(((multiling OR multilingue) or multilinguismo) or multiligues)({uml}uismo.\" or {uml}sismos.\")*".
• Removing quotes may allow a broader search: (((multiling OR multilingue) or multilinguismo) or multiligues)({uml}uismo. or {uml}sismos. )*.
