It's not true, is it?
My motto is, "I will not tell a lie."
Saying you won 100 million yen in the lottery sounds like a lie, I can't believe that!
The kanji and the word are exactly the same. A lie is a lie!
Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You learned with reading with the kanji, so you should be able to read it already!
