Definition Builder
Build clearer definitions by finding the class, the distinguishing feature, and the boundary cases. The tool walks you through the classical genus-differentia structure without requiring you to learn the Latin first, then helps stress-test your draft against ten common definition problems.
1. The term and your starting point
Start with the word you're trying to define and a rough first attempt. The first attempt is just a starting point — the rest of the tool is for refining it.
2. The class and what makes the term distinct
Most concepts can be defined by saying what kind of thing they are (the class) plus what distinguishes them from other members of that class (the distinguishing feature).
3. Examples and edges
Examples show what counts; non-examples show what doesn't; borderline cases test the definition's sharpness. List a few of each — one per line.
4. Draft definition
Built directly from the parts you wrote above. Edit the parts to change the draft.
