Perhaps you should try some spelling variations:
presentar » presentan, presentarse, presente, presenter, presentear
presentaron » presentanon, presentarseon, presenteon, presenteron, presentacion, presentation, presentan, presentearon
presenta » presente, presentea
presentada » presenteda, presentado, presentan, presenteada
presented » presente, presentan, presenteed
present » presente

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: (presentar OR (((presenta OR presentaron) OR (presentada OR presented)) OR present))~.
• Adding a wildcard symbol may retrieve word variants: (presentar or (((presenta or presentaron) or (presentada or presented)) or present))*.
