Onomatopoeia, it doesn't look like a real word but it is! Onomatopoeia is pronounced ON like onto, NO like nose, MA like marker, TOE like toes, P like the letter p, UH like under. An onomatopoeia is a word that is the same as the sound it's describing. For example if a volcano explodes, you could use the onomatopoeia "boom" to describe the sound. Or if you drop a glass and it breaks, you might use the onomatopoeia "crack". English isn't the only language that uses onomatopoeias, in Japanese you can describe a heart beating with the onomatopoeia "ドキドキ". Can you think of any other onomatopoeias in Japanese? Try to think of some in English!
