cyber + noun (e.g. cyber attack, cyber security)

Usage Note

Attributive only — always placed immediately before the noun it modifies. You say a cyber attack, not *the attack was cyber. Many common compounds (cybersecurity, cybercrime, cyberbullying) are now often written as single words.

Common Mistakes

I bought a cyber book.
I bought a digital e-book.
Cyber describes threats, security, and infrastructure, not ordinary digital content.
The attack was cyber.
It was a cyber attack.
Cyber as an adjective cannot follow a linking verb; it only appears before a noun.

Synonym discussion

Sense: adjective/1

All four words describe technology-related concepts, but they differ in scope. 'Digital' is the broadest term, covering any data stored or transmitted as binary signals — from digital cameras to digital textbooks. 'Online' is narrower: it refers specifically to being connected to the internet ('an online payment'). 'Virtual' focuses on simulated or computer-generated environments (virtual reality, virtual classroom) rather than security or criminal activity. 'Cyber' is the only word that strongly implies threats, defense, and infrastructure — you would say 'cyber attack' but not 'virtual attack' or 'digital attack' (unless you mean a numerical attack). In everyday use: 'I bought a digital book' (file format), 'I bought an online book' (purchased via the web), but 'the company suffered a cyber attack' (a security event).

Etymology

GreekEnglish

A shortening of 'cybernetics', which was coined in the 1940s by mathematician Norbert Wiener from the Greek word 'kybernetes' (κυβερνήτης), meaning 'steersman' or 'governor'. In the 1980s, the prefix 'cyber-' exploded in popularity through science fiction (cyberspace, cyberpunk), and by the 1990s it had begun to appear as a standalone adjective and noun in journalism and tech circles.
