multilingue » multilinguesue
{uml}iismo." » {uml}mismo.", {uml}sismo.", {uml}itsmo.", {uml}imismo.", {uml}isismo.", {uml}iistmo."
{uml}imismo." » {uml}asimismo.", {uml}animismo.", {uml}immismo.", {uml}imsismo.", {uml}imistmo."

• If you are trying to use Boolean operators, they must be ALL CAPS: "(multiling OR multilingue)(({uml}iismo." or {uml}imismo.") OR ({uml}ismo." or {uml}simo.")).
• Removing quotes may allow a broader search: (multiling or multilingue)(({uml}iismo. or {uml}imismo. ) or ({uml}ismo. or {uml}simo. )).
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingue)(({uml}iismo." or {uml}imismo.") or ({uml}ismo." or {uml}simo."))*.
