What does softener mean?
A softener is something that makes another substance, object, or effect less hard, harsh, or severe. The best-known meaning is a laundry product added during washing or drying to reduce the stiffness of cloth and leave it feeling gentler. A second familiar meaning is a water softener, an appliance that removes or replaces the minerals responsible for hard water. These meanings share the idea of reducing harshness: fabric softener softens the texture of textiles, while a water softener reduces the effects of mineral-rich water. The word is common in everyday English, especially as a modifier, but it can also be understood more generally as any agent that moderates a harsh quality, such as sound, light, or impact. Its usefulness lies in this combination of a specific everyday meaning and a broader metaphorical potential: whenever something needs to be made less severe, it can be described as functioning as a softener.

Where does softener come from?
The word was formed in English by adding the noun-forming suffix “-er” to “soften,” creating an agent noun for something that performs the action of softening. “Soften” in turn derives from “soft,” an English adjective inherited from Old English sōft. The related forms “softly” and “softness” also continue this inherited English root.
