What does cordoning mean?
"Cordoning" is the act of sealing off an area by forming a line — or "cordon" — of police officers, soldiers, or physical barriers around it, so that no one can enter or leave without permission. The term appears most often in journalism and official reports: authorities respond to a security threat, crime scene, protest, or hazardous spill by cordoning off the affected streets. The underlying noun, "cordon," entered English from French, where it meant a small cord or braid; over time it came to describe both a decorative military ribbon and, metaphorically, a line of troops standing shoulder to shoulder like a drawn cord. Today, "cordoning" retains that sense of deliberate, controlled restriction. It is a useful word for describing containment measures precisely — whether around a building, a border, or a hazard zone — and it signals an organized, authoritative action rather than a casual obstruction.
The action of encircling or blocking off an area with a line of police, soldiers, or barriers to prevent passage.
"The cordoning of several city blocks disrupted traffic for most of the day."
Frequently appears in the gerund phrase "cordoning off."
Present participle of "cordon": to surround or isolate an area with a protective or restrictive line of people or barriers.
"Security personnel were cordoning the venue hours before the summit began."
Almost always followed by "off" in modern usage.
Every time police 'cordon' a street, they're using a word borrowed from the military ribbon — the 'cordon' was originally a decorative braid worn on uniforms before it became a human chain.

Etymology of cordoning
"Cordoning" derives from the noun "cordon," borrowed from French, where it is a diminutive of "corde" meaning cord or string. The French word traces back through Old French to Latin "chorda" (and earlier Greek "khordē"), the same root that gives English "chord" and "cord." In English, "cordon" first referred to a narrow braid or ribbon worn as part of a military uniform, then came to mean a line of soldiers or police forming a barrier — as though people were strung together like a cord — from which the verb "to cordon" and its present participle "cordoning" developed.
