Perhaps you should try some spelling variations:
multilingues » multilinguismo
{uml}uismo. » {uml}mismo., {uml}iismo., {uml}uisme., {uml}umismo., {uml}uistmo., {uml}uiso.
{uml}ismo. » {uml}mismo., {uml}istmo., {uml}iso.
{uml}sismo. » {uml}smismo., {uml}sistmo., {uml}siso., {uml}sismos., {uml}mismo.
{uml}simo. » {uml}simon., {uml}sido., {uml}sino.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (multilingue or multilingues)({uml}uismo. or ({uml}ismo. or ({uml}sismo. OR {uml}simo.) ))~.

• Adding a wildcard symbol may retrieve word variants: (multilingue or multilingues)({uml}uismo. or ({uml}ismo. or ({uml}sismo. OR {uml}simo.) ))*.
