 The [`Clone`][clone] trait helps us do exactly this. Most commonly, we can
 use the `.clone()` method defined by the `Clone` trait.
 
+## Copy: Implicit Cloning
+
+The [`Copy`][copy] trait allows a type to be duplicated simply by copying bits,
+with no additional logic required. When a type implements `Copy`, assignments
+and function calls will implicitly copy the value instead of moving it.
+
+**Important:** `Copy` requires `Clone` - any type that implements `Copy` must
+also implement `Clone`. This is because `Copy` is defined as a subtrait:
+`trait Copy: Clone {}`. The `Clone` implementation for `Copy` types simply
+copies the bits.
+
+Not all types can implement `Copy`. A type can only be `Copy` if:
+- All of its components are `Copy`
+- It doesn't manage external resources (like heap memory, file handles, etc.)
