Absolutely
By All Means, Right And Wrong
adverb, noun
Absolutely an injustice! We must absolutely punish the perpetrator, by all means. First, though, we should probably define right and wrong.
This word means "absolutely" when it's used as an adverb, and that's the use you'll hear most in conversation. However, as a noun it means "right and wrong", as in whether something is right or wrong, or good or bad.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
