presentaron » presentacion, presentation, presentan, presentaaron
presenteedas » presentadas, presentees, presentedans, presentaeedas
presentaba » presentaban, presentada, presentara, presentaaba

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((presentedo OR presentaron) OR (((presente OR presenteedas) OR presentaba) OR present))~.
• Adding a wildcard symbol may retrieve word variants: ((presentedo or presentaron) or (((presente or presenteedas) or presentaba) or present))*.
