Here's how it works:
* "Ki" is used when referring to a singular noun that is *inanimate* (not a living person or animal).
* It attaches to the noun and changes slightly depending on the noun's starting letter.
Examples:
* Kitabu (book) -> Ki-tabu (my book)
* Chombo (vessel) -> Ki-chombo (my vessel)
* Ufunguo (key) -> Ki-funguo (my key)
So, "Ki" by itself doesn't look like anything, but it changes the word it's attached to, making it possessive.
