What does sag mean?
To sag is to droop, sink, or weaken. Used physically, it describes a surface or structure that bends downward under weight, age, pressure, or strain: the rope sagged, the shelf sagged, and the road began to sag. Figuratively, it applies to conditions that are losing force or value, such as sales, confidence, wages, or an economy. The related noun describes both the physical droop itself and a broader decline, as in “a sag in demand” or “a sagging market.” The word is especially useful because it suggests a gradual weakening rather than an abrupt collapse, although it can refer to a sharp fall when the context requires it. In everyday use, sag also has the informal implication of becoming tired or losing enthusiasm, as when someone says their energy is sagging after a long day.

Etymology of sag
The word is inherited from Old English, where sagan meant “to sink, fall, or droop.” It developed into Middle English with closely related meanings concerning sinking, weakness, and loss of level or strength. Modern figurative uses, such as describing declining sales or an economy, are natural extensions of the original physical sense.
