Label the relationship
Inheritance, borrowing, derivation, meaning change, and conceptual correspondence are recorded as different claims.
Methodology
How claims are reviewed.
Language history includes uncertainty, competing accounts, and reconstructed forms. We label those differences and show the source attached to each claim.
Show direction clearly
Paths read from earlier to later, while the data also preserves which form is the source of a relationship.
Record support separately
The type of a claim and the strength of its evidence are recorded independently.
Show competing accounts
Different explanations can appear side by side, with the evidence for each one.
Mark the gaps
When evidence or data is missing, the interface says so.
Link answers to sources
Factual answers link back to the relevant words, relationships, and sources.
