What does uncoil mean?
Uncoil means to reverse the action of winding: a rope, cable, hose, spring, or other flexible object is unwound from a loop, spiral, or roll until it extends or straightens. The verb may be used transitively, as in “uncoil the rope,” or intransitively when the object uncoils itself. It is especially common in nautical, mechanical, industrial, and instructional language, although it is also used in descriptive prose and is understood in general English in both British and American usage. Uncoil can occasionally carry a figurative suggestion of straightening, extending, or gradually unfolding. Its formation is transparent: the prefix un- reverses the action of the older word coil. The word is therefore useful when precision matters, distinguishing the unwinding of a particular object from the more general idea of movement, reversal, or relaxation.
verbTo unwind a rope, cable, spring, or similar object from a coiled or rolled state. It can also be used intransitively for such an object to straighten or unroll itself.
- To unwind or straighten something from a coiled, rolled, or tightly curved state.
"The deckhand uncoiled the anchor line and lowered it carefully into the water."
"The deckhand uncoiled the anchor line before lowering it into the water."
"The spring uncoiled with a sharp metallic snap."
Sometimes the simplest words work in reverse: uncoil turns a compact spiral back into a loose line.
