What does loosener mean?
A loosener is a person, device, or mechanism that makes something less tight or releases tension, pressure, or restraint. Its meaning depends somewhat on context: in a technical setting, it may refer to a tool intended to undo a fastening or relieve pressure, while in an informal or occupational setting it can describe someone whose role is to ease a difficult situation. The term is most commonly used before another noun, forming expressions such as pressure loosener or tension loosener. Although understandable in general English, it is less frequent than the corresponding verb, loosen, and may sound somewhat technical or deliberately descriptive. The word is especially useful when the emphasis is not merely on the act of loosening but on the person or mechanism that causes the release.

Where does loosener come from?
The noun was formed by adding the agentive suffix -er to the verb loosen, producing a term for a person or thing that performs that action. Loosen developed from Middle English losen and is historically related to loose. The wider vocabulary of lax, laxative, and relax also belongs to the same Indo-European root concerned with loosening, unbinding, or being slack.
