"Disadvantaged" means someone who has less of the things they need to live a happy and healthy life. It's like when you have fewer toys to play with than your friends, or when you can't go on a fun trip because your family doesn't have enough money. Some people are disadvantaged because they were born into families that don't have a lot of money or because they live in parts of the world where it's hard to get the things they need, like clean water or good schools. We should try to help people who are disadvantaged by sharing what we have, being kind to others, and supporting organizations that help those in need.
