Yoda spoke backwards because when he was young (remember, that was some 800 ish years ago), that was the generally accepted way to speak Basic (the primary language of the star wars universe). In typical old person fashion, yoda continues to talk this way despite changing trends in the language.
When we hear characters in the Star Wars universe speaking English, they're really speaking Galactic Basic. There are various accents and dialects, but the most famous variant may be Yoda's, which changes the word order of Galactic Basic Standard.
This led Filoni to keep Yoda to only speak backwards because his master did, which makes sense for several reasons. His master could've spoken in riddles based on their species or the common language several centuries earlier spoke like that, leaving Yoda to speak like everyone else.
If Yoda's master did teach Yoda to use a backward way of speaking, it clearly helped him become a better Jedi. That's why Yoda also adopted a weird way of speaking -- so he could help train countless other Jedi and impart his wisdom to them.
Minch Yoda, known by most as simply just Yoda, was a legendary Groglyn male who was regarded as one of the most renowned and powerful Jedi Masters in the history of the Jedi.
Some decided that this is just the way his species speaks (a species that is still draped in mystery), but now fans know it's not that simple. In the latest issue of his ongoing comic, Yoda proves that he can speak 'normally', but actively chooses to speak in his now-iconic fashion.
Yes, in the Mandalorian, Grogu's age is revealed to be 50 in human years, Djin Djardin's age is never revealed but from the final scenes of the final episode of Season 2 of Mando, where Mando removes his helmet, an estimate of his age would be around 35-40 years. By the time of The Mandalorian, Grogu is 50.
Din Grogu, known only as Grogu until being formally adopted by Din Djarin after the conflict on Mandalore, was a male Force-sensitive Mandalorian belonging to the same mysterious species as the legendary Grand Master Yoda.
To be clear, Grogu is not a younger version of Yoda since "The Mandalorian" is set after "Return of the Jedi," in which Yoda (played by Frank Oz) died. They are, however, of the same species — but that species has not yet been revealed. There are more similarities between Yoda and Grogu than just looks.
Yoda was one of the most powerful Jedi Masters to ever live, whose amazing abilities could have been terrifying if he had ever turned to the Dark Side of the Force. However, even without actually turning evil, Yoda was still able to inadvertently bring about the fall of the Jedi Order by the end of the Clone Wars.
"[Yoda voice actor and puppeteer] Frank Oz told me once that Yoda speaks that way specifically in honor of his own master. That was what he had thought about it. I try to keep moving forward [with] these thoughts. And [Yaddle voice actor] Bryce [Dallas Howard] on her own made a great Yaddle.”
Yoda's age at death, a hasty 900 years old, reveals the absurd constancy of his species. This fantastic life span sheds ablaze on the mysteries of the Star Wars universe. His continued activity accustomed him to coach endless Jedi, including the allegorical Luke Skywalker.
Given that Grogu, Yoda, and Yaddle are the only known canon members of their species, it makes sense why some would try to draw a connection between the three of them. While Star Wars hasn't disproved the theory, it's highly unlikely that Yoda or Yaddle were Grogu's biological parents.
It was believed that Grogu would eventually become a victim of Kylo Ren's destruction of Luke's Jedi Order. However, The Book of Boba Fett revealed that Grogu chose to follow the Way of the Mandalorian rather than become a Jedi, sparing him from Kylo Ren's wrath.
So for every 10 years of Yoda's species would equate to 1 human year. So Grogu would be the equivalent of a 5 year old human and Yoda would equate to an elderly 90 human years.
Although, the two didn't really like each other at first, Yoda and Yaddle eventually grew very close, and over time their relationship even blossomed into a long lasting romance until Yoda's own death. The two had one son, Yoder Minch, a Jedi Master who would have a profound impact during the Yuuzhan Vong War.
We learned he was a male after Doctor Pershing referred to Baby Yoda as "him" in the third episode. And we know he is 50 years old, but because his species ages slowly, he is still considered an infant.
All the official Star Wars merch calls him The Child. On the show, they call him The Asset. What gives? The short answer is that “Yoda” is the name of a character, not a species, and the character we see on The Mandalorian is different from the Yoda we know and love from the Star Wars movies.
Most viewers have forgotten that Palpatine seems to have been afraid of Yoda in Star Wars: Episode III - Revenge of the Sith - and even tried to flee from their duel.
*189 of the world's languages do not have a dominant word order (source). Yoda typically speaks in the OSV order, which is only found in 0.3% of languages. “Powerful (object) you (subject) have become (verb). The dark side (O) I (S) sense (V) in you.”
