Difference Between Highjack and Hijack

Key Differences

Highjack is not a standard term in American English and is commonly considered a misspelling of "hijack." Hijack, on the other hand, specifically refers to the act of taking control of something, usually a vehicle, through force or by threat of force. This term is widely used in contexts related to air, sea, or land transportation.
While highjack is sometimes used in informal contexts or seen in older texts, it does not carry a specific, recognized meaning separate from hijack. Hijack is the correct spelling used in legal, military, and civil aviation contexts to describe the unlawful seizure of an aircraft or other vehicles.
In the realm of technology, the term hijack has also been adapted to describe the unauthorized takeover of computer systems or internet sessions, known as "session hijacking" or "DNS hijacking." There is no equivalent technological use for highjack, highlighting the importance of using the correct term "hijack" in these contexts.
The confusion between highjack and hijack likely arises from variations in regional spelling and pronunciation. However, standard English language resources and dictionaries list hijack as the correct form. Thus, in written and formal communication, hijack should be used to ensure clarity and correctness.
Understanding the difference between these terms is crucial for clear communication, especially in safety and security-related discussions. The use of hijack in all official and formal contexts helps maintain consistency and avoids misunderstandings.
