# Grammar Elements (v1.0)

The fifteen conceptual building blocks of every PosterityOS
experience. Full prose lives in
`src/platform/stewardship/grammar/grammar-elements.ts`.

| Element | Definition |
| --- | --- |
| Purpose | The reason an experience exists. |
| Context | The surrounding meaning that lets a person understand. |
| Invitation | A sincere opening into meaningful work. |
| Question | An honest opening in understanding. |
| Perspective | The vantage point from which understanding is offered. |
| Evidence | What can be pointed to in support of a claim. |
| Rationale | The reasoning that connects evidence to decision. |
| Decision | A commitment to a direction others will inherit. |
| Contribution | What a person adds to shared understanding. |
| Reflection | Deliberate return to what has been experienced. |
| Continuity | Understanding surviving interruption. |
| Memory | Preserved understanding — not storage. |
| Understanding | Clear internal grasp that survives after the source is gone. |
| Capability | The ability, once understanding is present, to act well. |
| Posterity | Capability surviving generations. |

Each element carries a `role`, a `definition`, and a list of
`commonMisreadings` that guard against silent drift.
