More Verbs - To Be

There are two new verbs, ある and いる that I can use to explicitly describe the state of being for nouns. They don't express an action, but sort of represent the equivalent of "to be" or "there is" in English. I believe I said this in another post, but ある is generally for inanimate objects, while いる is for living things.

お金はあるですか？
Is there money?

アヤト君は私の家にいる。
Ayato-kun is at my house.

リーさんは学校にいる。
Lee-san is at school.

君の毛布は机の上にある。
Your blanket is above the desk.

ライト君はどこにいる？
Where's Laito-kun?

These are pretty simple to use so far, and the に particle is common here because it's being used as an "at" to say "this noun exists at this place."
