Wisdom
Intelligence
noun
You are favored with knowing things. You have wisdom and intelligence.
This is a jukugo word, which usually means on'yomi readings from the kanji. You didn't learn 知's on'yomi when you learned the kanji, so here's a mnemonic to help you:
Your wisdom tells you people should eat cheese (ち) on a regular basis. Yes, in your infinite wisdom, you know that a calcium-rich food like cheese is just what humanity needs. It is your duty, O wise one, to share this wisdom with others. Go forth! Spread the wisdom of cheese consumption with all mankind!
