The word "grounding" derives from the Old English "grund," meaning "bottom, foundation, or earth." The suffix "-ing" transforms the verb "ground" (to connect to the earth or to restrict movement) into a noun. Historically, the concept of grounding evolved from literal connections to the earth (e.g., electrical safety) to metaphorical foundations (e.g., education) and disciplinary restrictions.
