-- Create a reorderable state by  `rememberReorderableLazyListState` for LazyList or `rememberReorderableLazyGridState` for LazyGrid
+- Create a reorderable state by `rememberReorderableLazyListState` for LazyList or `rememberReorderableLazyGridState` for LazyGrid
 - Add the `reorderable(state)` modifier to your list/grid
-- Inside the list/grid itemscope create a `ReorderableItem(state, key = )` for a keyed lists or `ReorderableItem(state, index = )` for a indexed only list. (Animated items only work with keyed lists)
+- Inside the list/grid item scope create a `ReorderableItem(state, key = )` for keyed lists or `ReorderableItem(state, index = )` for an index-only list. (Animated items only work with keyed lists)
 - Apply the `detectReorderAfterLongPress(state)` or `detectReorder(state)` modifier to the list.
 If only a drag handle is needed apply the detect modifier to any child composable inside the item layout.
