Declamation is when someone talks or reads out loud in a very passionate and expressive way. It's like they are acting out a story or a speech! Imagine you're playing with your toy cars or dolls and you're making them talk to each other in different voices - that's a bit like what declamation is, but for grown-ups!
When people do declamation, they often choose a famous speech or poem to read out loud. They might practice over and over again to make sure they get all the words and tones just right. Then, they stand in front of an audience and read it out loud with lots of energy and emotion.
Some people even compete in declamation contests, where they try to be the best at reading out loud. It can be really fun to watch and listen to people who are really good at declamation!
