During the prequel era, Jedi Master Yoda was a member of the Jedi Council, even serving as Grand Master of the Jedi Council. In the twilight days of the Order, he taught the very youngest Jedi, but Count Dooku had once been his Padawan.
Yoda’s speech is in OSV (object–subject–verb) syntax, as opposed to the standard English SVO (subject–verb–object.) Linguists on Reddit have created a list on how other languages translate his dialogue.
We don’t know what species Yoda is, or what planet he’s originally from - it was off-limits even in the Expanded Universe.
