Perhaps you should try some spelling variations:
verba » verbal, vera, yerba, verboa, veraa, verya
deras » demas, duras, heras
vers » verso, verse, versa
verbos » verbo, verboos, veraos, veryos, vverbos, verbs, varbos
verb » verbo, vera, very
erbo » verbo, erb, arbo
vero » veron, verso, verbo

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "Russian (((verba OR (deras OR vers)) OR verbos) OR ((verb OR (era OR ver)) OR (erbo OR vero)))~".
• Adding a wildcard symbol may retrieve word variants: Russian (((verba OR (deras OR vers)) OR verbos) OR ((verb OR (era OR ver)) OR (erbo OR vero)))*.
