aru Kanji confusion

In the sentence:

今日は宿題があります。

would I use

在る or 有る?

(I know that today it's almost always written in Kana) Thanks in advance :)!

Answer

有る is for possession; 在る is for existence. Though there can be some overlap. And 或る (even though you didn't ask) is actually an adjective for "a particular/certain", like in ある日に....

So in this case, I'm mostly certain it would be 有る since you "have" homework.

Here are some words that might help remember the difference:

有

• 所有　→　one's possessions; ownership



• 有罪　→　guilty; "having" guilt


• 共有　→　sharing; joint ownership


• 有料　→　something that costs money (as opposed to free 無料); "having" a cost


• 有力　→　strong; influential; "having" power

在

• 所在　→　whereabouts


• 存在　→　existence


• 在日　→　living/staying in Japan (particularly used for foreigners)



• 現在　→　the present (time)


• 在庫　→　inventory (merchandise)
