What does flee mean?
"Flee" is a verb meaning to run away hurriedly from a place, person, or situation, typically because of fear, danger, or pursuit. It is among the most urgent words in English for departure: unlike neutral terms such as "leave" or "go," it implies that staying would bring harm. People flee war zones, persecution, burning buildings, or the scenes of crimes; one may flee a concrete danger or, more figuratively, flee responsibility or an uncomfortable truth. Grammatically, "flee" takes either a direct object — "they fled the country" — or the construction "flee from," and its past tense and past participle are both "fled." The word descends from Old English "flēon" and ultimately from an ancient Indo-European root meaning to run or flow, which it shares with "flow." Its connotations of desperation make it central to writing about refugees, emergencies, and escape.

"Thousands of residents fled the coast ahead of the approaching hurricane."
"The refugees fled their village when the fighting drew near."
"He fled the scene of the accident before the police arrived."
"Flee" traces back thousands of years to an ancient Indo-European root meaning "to run or flow" — making it a distant cousin of the word "flow," as if language itself knew that running away and water pouring share the same urgency.

Etymology of flee
"Flee" descends from the Old English strong verb "flēon," meaning to run away, which in turn goes back to Proto-Germanic roots shared with continental relatives such as German "fliehen" and Dutch "vluchten." More distantly, it stems from an ancient Indo-European root meaning to run or flow, a lineage it shares with the English word "flow" and, by many accounts, with Latin verbs of flowing such as "fluere," the source of "fluent." The word has kept its core sense of rapid escape essentially unchanged across more than a thousand years of English.
How flee is actually used
"Flee" carries a strong sense of urgency and usually implies fear or threat, distinguishing it from the more neutral "leave." It takes a direct object (what or where one flees) or the phrase "flee from," though plain "flee from" can sound slightly formal or literary. The past tense and participle is "fled."
Easily confused with flee

"Free" (/friː/) sounds very similar to "flee" (/fliː/) but means not being held captive or costing nothing, rather than running away.
