If something is 'sacrificeable,' it means it can be given up or surrendered, often for a greater cause or to achieve a particular goal. It implies that the thing in question is not essential or can be replaced without causing critical harm. Think of it as a calculated loss for a potential gain. It doesn't necessarily mean the item is worthless, but rather that its value is outweighed by the potential benefit of sacrificing it. A character's pawn in chess is sacrificeable to gain a strategic advantage.
