The word 从未 is formed through the conceptual fusion of its two component characters: 从, which means "from", establishing a point of origin or a span of time, and 未, which means "not yet" or "never", expressing negation or non-occurrence. Their combination creates a new, unified idea that is more than the sum of its parts, pictorially representing the negation of any event across the entire timeline stretching from a starting point (which is often implied as the past) right up to the present. It is a spatial-temporal metaphor where "from" sets the scope and "never yet" fills that scope with absence, forming the complete concept of "never (at any point from then until now)".
