Hey there, kiddo! So, the word "burgh" (sometimes spelled "burg") means town or city.
Imagine a big place with lots of tall buildings and people walking around everywhere. That's a burgh!
You might hear people say "Edinburgh" or "Pittsburgh," those are both burghs.
Basically, any place that has a lot of people living and working together in a community can be called a burgh. Kind of like a really big neighborhood!
