Pronunciation: [wˈɜːkɪŋ lˈuːs] (IPA) 
The correct spelling of the phrase "working loose" can be a bit confusing because it contains a silent "k" and an "e" at the end. In IPA phonetic transcription, it can be written as /ˈwɜrkɪŋ luːs/. The "k" in the word "working" is silent, so the stress falls on the first syllable. The "e" at the end of "loose" is also silent, but it serves to indicate that the "s" is pronounced with a soft "s" sound.
Working loose refers to the gradual or progressive detachment or release of a component, fastening, or object from its initial secure or fixed position, resulting in a less stable or secure state. It is commonly used to describe the condition or action where something that was previously tightly affixed becomes gradually unfastened or less secure over time due to repeated use, movement, or external factors.
When an object or part is said to be working loose, it implies that it is no longer tightly or securely held in place, and there is a risk of it becoming fully detached if not attended to or rectified promptly. This phenomenon is often encountered with fasteners, screws, bolts, or other mechanical connections, which can progressively lose their grip or tightness due to vibrations, constant usage, wear and tear, or other external forces.
Working loose can also be used to describe the action of actively or deliberately dislodging or detaching a component from its original position. This is often done intentionally by individuals for maintenance or repair purposes, such as loosening a bolt to remove or replace a part. In this context, working loose refers to the act of deliberately making a connection less secure or tight in order to facilitate its disconnection or alteration.
The phrase "working loose" does not have a specific etymology as it is a combination of two separate words/phrases. "Working" typically refers to the action of doing something, such as performing a task or job. "Loose", on the other hand, means not firmly or tightly fixed in place. When put together, "working loose" generally means to become unfastened or undone while doing a particular job or activity.
