EU AI Act

A law that applies to all European Union Member States and establishes a risk-based framework; the law imposes strict controls on 'high-risk' AI applications and prohibits 'unacceptable-risk' uses of AI

The Explain card

Plain English
The EU AI Act is a law applying across all EU Member States that regulates AI by risk tier. It prohibits "unacceptable-risk" uses and imposes strict obligations on "high-risk" applications.
Example
A recruitment company sells an AI tool that ranks job applicants. Because employment decisions are treated as high-risk, the vendor must implement risk management, data governance, logging, human oversight and documentation before placing it on the EU market.
Why it matters
For defenders, the Act turns good practice into legal obligation. Knowing which tier a system falls into tells you what controls and evidence you must have ready before regulators ask.
Hook
Traffic lights for AI: red is banned, amber is heavily controlled.

Word knowledge

How the word is built, where it came from, and what it sits beside in memory.

In a sentence

Before CE-marking a diagnostic scanner, the manufacturer lodges the EU AI Act technical documentation with the notified body.

Why these words
  • EU English initialism of European Union, from Europe and Latin unio, oneness places the statute in the Union rather than in a single Member State
  • AI English initialism of artificial intelligence, from Latin artificialis and intelligentia names the domain the statute governs
  • Act Latin actus, a doing, from agere, to do supplies the head noun that marks the phrase as a statute's short title
Where it came from
Origin
English short title from the initialisms EU and AI plus Act, Latin actus, a doing; in English law, a statute
Entered the language
c. 2021
What changed
Act has named a parliamentary statute in English since the 1400s. The 2021 Commission proposal parenthesized Artificial Intelligence Act as a short title. English compliance writing then prefixed EU so the Union instrument would not be confused with national AI bills, and the three-word label stuck through the 2024 adoption.
How it is spelled
Pattern
Two-letter initialisms are written in all caps with no points
Pattern
Statute short titles capitalize Act even mid-sentence
Pattern
The three tokens stay space-separated with no hyphen
Breaks the pattern
older prose still writes E.U. with points, but the short title drops them
Breaks the pattern
the Official Journal citation is Regulation (EU) 2024/1689, not the three-word label
