It's important to note that in Kikuyu, there are different ways to say "you" depending on the context and formality:
* Nyinyi: This is the most common plural form of "you." It's used in formal settings and when addressing multiple people.
* Ninyi: This is a more informal plural form of "you." It's used with friends and family.
* Mũthemba: This word is used when addressing a group of people in a respectful way, like "you all" or "your group."
So, "nyinyi" is already the correct way to say "you" (plural) in Kikuyu.
