To Be Rich
To Be Wealthy
intransitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means rich so the verb vocab version would be to be rich.
とむ
Think about the richest person you know. That person is Tom (とむ). Imagine Tom as being super rich. If you don't know a Tom, think of a famous Tom, like Tom Cruise, who definitely is pretty rich.
