So, imagine you and your friend work on a cool school project together. You both do some work on it and make it really awesome. When you're finished, your teacher asks who did the project. You and your friend both raise your hand and say "we did!"
That's kind of like academic authorship. When people work on a project or research paper together, they might all have different parts they contributed to make it great. When it's done, they all want to get credit for the work they did. Just like you and your friend both got credit for the school project you worked on together.
In academic authorship, all the people who worked on the project are listed as authors. But sometimes, people will do more or less work than others. So, just like your teacher might ask who did what on your school project, other people want to know who did what on the research project. That way, they can know who to give credit to for each part of the project.
Academic authorship can be really important for people who want to get jobs or promotions in their field. If someone is listed as a main author, that means they did a lot of the work and they might get more credit for it. But even if someone isn't listed as a main author, they still get some credit for helping with the project.
Overall, academic authorship is about making sure everyone gets credit for the work they did on a project or research paper. Just like you and your friend got credit for the school project you worked on together!
