What is the topmost node of a decision tree called?

In a decision tree, the topmost node is called the root. It serves as the starting point from which all splits begin and from which every other node descends. The root contains the initial question or feature used to partition the data, and the path from the root through branches leads to the final predictions. Leaves are the terminal nodes that show the outcome, while a branch connects a node to its child. A node is any point in the tree, including the root, internal nodes, and leaves. So the topmost node is designated as the root.
