Yoda (voiced by Frank Oz) is a fictional character from Star Wars universe, who appears in all of the franchise's films except for Star Wars Episode IV: A New Hope. As with many names in Star Wars, the name "Yoda" may have been etymologically derived from an ancient language – in this case, possibly from the Sanskrit noun yoddha ("warrior"), or from the Hebrew verb yodea ("knows"). Other etymological theories exist as well (see Etymology below).
