Argument moves
Definition Capture
The fight is over whose definition of a term governs — recession, hate speech, foreign interference, fair use.
What It Is
Definition Capture fits when the visible argument hangs on a single contested word, and the substance of the dispute is who gets to define that word for legal, regulatory, or social purposes. The definition is not downstream of the argument; it is the argument.
Readers often debate the application of a category without realizing the boundary of the category was just contested. Naming Definition Capture surfaces moments when winning the linguistic ground decides what happens before any specific case is judged.
How To Spot It
One actor proposes a standard for what a term means; if accepted, that standard binds future disputes. The story's news is the definition move, not any particular fact under the new definition.
- Legal arguments over the meaning of 'platform,' 'publisher,' 'search,' 'AI'
- Regulatory definitions of 'recession,' 'small business,' 'essential worker'
- Speech debates over 'harassment,' 'incitement,' 'disinformation'
- Standards bodies adopting one definition over a competing one
Microsoft AI chief criticizes Anthropic’s Claude training approach
Microsoft's AI chief criticizing Anthropic's Claude training approach isn't just a personality dispute—it's a contest over whose definition of 'safe' or 'responsible' AI training becomes the standard other labs are measured against.
False Positive
Routine vocabulary disputes are not this species. The signature is when the definition, once captured, decides the next several rounds of policy or enforcement.

Trump calls Iran conflict 'small potatoes,' backs Vance's refusal to call it a war
Calling the Iran conflict 'small potatoes' and endorsing the refusal to term it a war is a fight over a word with legal weight, since 'war' triggers War Powers reporting and congressional authorization. Whoever's vocabulary sticks governs which oversight machinery ever switches on.
