Question: does yaddle talk like yoda?
Answer: Yaddle never speaks in the film, but in several non-canonical comic books published by Dark Horse, Yaddle talks with the same distinct speech patterns as Yoda. So, if we take Yaddle's speech as proof, then Yoda's speech patterns might be somewhat cultural. ... In Return of the Jedi, Yoda tells Luke he's 900 years old.
