capstone
This term evokes the image of a final, locking piece that provides structural integrity and completion. In a physical sense, it refers to the topmost stone of a wall or pyramid, serving as both a functional seal and a visual signal of finished work. In professional or academic contexts, it describes a peak achievement or a synthesis of learning. A capstone project is not merely a final assignment but a comprehensive demonstration of mastery that binds together disparate skills acquired over time.
