What does hack mean?
Hack is a versatile word whose meanings have expanded far beyond its original sense of cutting roughly with repeated strokes. Today, its best-known use is in computing: to hack a system is to gain unauthorized access to it, while a hack can also be a program that exploits a weakness or an intrusive piece of code. The word can further describe writing or work that is careless, unoriginal, or technically crude, as in “a hack job,” and it can be used approvingly for an improvised solution, as in “life hack.” As a noun, hack may refer to a computer intruder, a mediocre worker, an unoriginal writer, or a useful shortcut. The verb also retains the older physical meaning of cutting or chopping roughly. Although some uses are neutral or complimentary, the word often carries a dismissive or derogatory tone when applied to people’s work.
A computer intruder or program that gains unauthorized access to a system; also, a crude or unoriginal piece of work, a person who performs routine work poorly, a practical workaround, or a rough cut.
"The company hired a specialist to investigate the hack and strengthen its defenses."
To cut or chop roughly; to gain unauthorized access to or manipulate a computer system; to create or modify something in an unoriginal or technically crude way; or to improvise a practical solution.
"They hacked a quick script to automate the repetitive task."
The plural is used for individual computer intrusions, crude pieces of work, or practical shortcuts, as well as for people described as mediocre workers.
"The publication published several popular life hacks for saving money."
One word can mean both an axe-like chop and a breach of digital security: a hack started as a way to cut and gradually became a signature of computer intrusion.

Where does hack come from?
The word descends from Old English hacian, meaning “to cut, cleave, or hack,” through Middle English hacken. Its Germanic relatives include German hacken, Dutch hakken, Danish hakke, and Swedish hacka. The computing senses developed much later by extending the idea of working on a system in an intrusive or technically unconventional way.

How hack is actually used
The computing sense is now especially prominent and is usually informal or technical. In creative and professional contexts, calling something a hack or describing someone as a hack is often dismissive, suggesting that it is unoriginal, careless, or technically crude; however, “hack” can be approving when it means an ingenious, improvised solution. The verb “hack” in the sense of cut is more common in traditional, technical, or literary contexts than in everyday modern speech.
