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
New York sues Polymarket over alleged unlicensed gambling
New York's suit against Polymarket turns on whether prediction-market contracts count as 'gambling' — the real stakes are which definition of that term will govern how such platforms can operate everywhere else.
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.
