Perhaps you should try some spelling variations:
verba » verbal, vera, yerba, veraa, verya
verbes » verdes, verbos, verges, veres, veraes, veryes
verbo » vero, verao, veryo, verb, varbo, vebbo
verb » ver, vera, very
sera » ser, sea, sara
erbo » erb, arbo, ebbo
verso » versos

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 (verbes OR verbo)) OR ((verb OR ((sera OR vega) OR era)) OR (erbo OR verso)))~".
• Adding a wildcard symbol may retrieve word variants: Russian ((verba OR (verbes OR verbo)) OR ((verb OR ((sera OR vega) OR era)) OR (erbo OR verso)))*.
