A suburb is a part of a city that's outside the main center but still close by. It usually has its own shops and houses.
When we talk about suburbs, we often mean areas where people live in houses or apartments with big gardens, instead of apartments in the city center. The idea is that it's quieter and more peaceful than living right downtown. Suburbs are popular for families because there's often a lot of space for kids to play outside and parks nearby. Some suburbs can feel quite separate from the rest of the city, but they still have easy access to public transport and amenities like shops and schools.
A residential area located on the outskirts of a city or large town that usually includes businesses that cater to its residents; such as schools, grocery stores, shopping centers, restaurants, convenience stores, etc.
