noose
Synonym discussion
Sense: noun/1
While all four words involve rope or cord, each names a different thing. A loop is any curved shape in a rope — it does not tighten on its own, and it has no specific purpose. A noose is a loop with a slipknot that tightens when pulled; its strongest association is with execution, which gives the word a dark tone. A snare is a trap, often using a noose-like mechanism, but the focus is on the act of catching rather than the knot itself. A lasso is a long rope with a noose at the end, thrown to catch cattle or horses; it differs from a noose in its purpose (animal wrangling) and its method (throwing from a distance). A knot is a broad term for any fastening made by tying rope — neither a specific shape nor a tightening mechanism. For example, you untie a knot but you cut a noose; you throw a lasso but you set a snare.

Etymology
The word 'noose' entered English around the 1400s from Middle English 'nose' or 'noos', which came from Old French 'nos' or 'nouz' meaning 'knot'. The Old French word traces back to Latin 'nodus', also meaning 'knot', which is the source of English words like 'node', 'nodal', and 'knot' itself. The original sense was simply a loop or knot in a rope; the specialised meaning of a slipknot used for hanging developed over time as the word entered legal and execution contexts.
