This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb.

The kanji 受 means accept and this verb is related. It means to get accepted, usually into something good like a university or a new job. It can also mean to succeed or to pass, often in the context of a test or an exam.

This is an intransitive verb, meaning it happens on its own. The かる ending is a hint, because verbs with かる as okurigana (kana added to the kanji) are usually intransitive.

Watch out: whereas in English we'd say "to pass an exam", in Japanese it's 試験に受かる, or "to pass in an exam". That's why it's intransitive in Japanese, even though we might make it transitive in the English translation!
