How Much
adverb, noun
This has the same meaning as the kanji, specifically the how much meaning. To remember this, just think about how Ra, the Egyptian God, is always asking "How much will it cost to build this pyramid?" Ugh, too much, let's hire some slaves.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading already so you should be able to read it!
