Here's why:
* Directional processes describe movement or change from one point to another. The word "to" indicates this directionality, showing where the movement or change is heading.
* Examples:
* "The car drove to the store." (Movement)
* "The caterpillar transformed to a butterfly." (Change)
While "to" is commonly used, other words can also indicate direction, depending on the specific context. These can include:
* Toward: "The bird flew toward the tree."
* Into: "The ball rolled into the hole."
* Across: "The children ran across the playground."
* Through: "The river flowed through the valley."
