Dictionary Entry
hijack /ˈhaɪdʒæk/ (HY-jak), verb (also spelled highjack)
- To seize control of a vehicle, especially an aircraft, by force or threat.
- To take over or take control of something for one’s own purposes (“hijack the meeting”).
- noun: an act of hijacking.
Hijack Meaning in Simple Words
At its heart, hijack means a hostile takeover. Someone grabs the controls, literally or figuratively, and steers things where they were not meant to go.
The original sense is the scariest: armed people seizing a plane. But the word escaped that box decades ago. Dictionary.com’s entry lists the classic senses: stealing cargo from a truck, robbing a vehicle, seizing it by force. Today you can hijack a meeting (derail it with your agenda), hijack a thread (drag an online discussion off-topic), hijack a computer (malware seizing control), or hijack a movement (a cause taken over by outsiders). Cambridge Dictionary gives both the violent and the everyday senses: seizing a vehicle, and disapprovingly taking control of something for your own advantage. See Cambridge’s entry for hijack.
The Many Faces of Hijack
The original: vehicles. Planes, trucks, ships. Force or threat, physical danger. This is the sense that made the word famous, and the one laws are written around.
The meeting hijack. No weapons, just one person with an agenda. “He hijacked the standup to complain about parking.” Everyone has lived this. The meeting had a purpose; now it has a hijacker.
The threadjack. Online, a hijacked thread is a discussion dragged off-topic. Forums even coined “threadjack” as its own word. The conversation was about gardening; now it’s about politics.
The digital hijack. Malware that seizes your browser, your files, your webcam. “Browser hijackers” redirect your searches. “Cryptojackers” steal your computer’s power to mine crypto. The violence is gone; the takeover logic is identical.
The political hijack. Wiktionary even lists a technical sense: legislators “hijacking” a bill by deleting its contents and inserting new provisions. Democracy’s version of seizing the controls.
Hijack vs Carjack vs Skyjack
English built a whole family from this word:
Hijack is the general term: seizing any vehicle or process.
Carjack (or carjacking) is specifically stealing a car from its driver by force. Coined in the early 1990s, it narrowed hijack to automobiles.
Skyjack is the older synonym for aircraft hijacking, popular in the 1970s when plane hijackings filled the news. It has mostly faded, replaced by “hijack.”
Think of hijack as the parent, carjack and skyjack as the specialized children, and that family tree is hijack meaning branching out over a century.
Where the Word Came From
The hijack meaning origin is delightfully murky. The leading theory: a blend of highway + jacker (one who holds up), from around 1915, when “highjackers” robbed trucks and bootleggers during Prohibition. Before planes, hijackers stole whiskey shipments. The word then climbed into the sky with the age of air travel and never came down.

Key Takeaways
- Hijack meaning: to seize control by force or without permission, vehicles first, now meetings, threads, computers, bills.
- Pronounced HY-jak; possibly from highway + jacker, circa 1915 (Prohibition-era truck robbers).
- Carjack = cars specifically; skyjack = planes (dated). Hijack covers all.
- The figurative senses (meetings, threads) are now more common in daily speech than the literal one.
Final Thoughts
Hijack is a word that traveled from the highway to the sky to the conference room to the internet without losing its meaning. Everywhere it goes, it names the same human move: grabbing what is not yours and steering it your way.
It’s worth knowing the hijack meaning precisely, because the milder senses sneak up on people. Nobody announces “I am about to hijack this meeting.” They just start talking. Now you have the word for it, and naming it is the first defense.
