To Get Angry, To Get Mad
intransitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means angry, the verb vocab version is to get angry.
おこる
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: You're starting to get angry about something. It's mostly this okra (おこ). It tastes terrible.

ごめんってば。そんなに怒らないでよ。
I'm sorry. Please don't get so angry.
