A constituency is like a group of people who live in a special area called a district or a voting area. It is like a big team where every person in that area is part of that team, and they choose someone to represent them. This person is called a Member of Parliament (MP), and their job is to listen to the team's concerns and ideas and to help make decisions for the good of the team. The team members can vote for their favorite MP, and the person with the most votes will become their representative. The MP will work together with other MPs from different constituencies to make decisions that will help everyone in the country live better.
