The case record
What was reported?
Thousands of short inscriptions from the Indus civilisation remain without an agreed decipherment. Their brevity and uncertain language make this a problem of evidence and method, not an absence of sophisticated ancient communication.
Signs appear on seals, sealings, tablets and other objects distributed across a large urban and trading world in present-day Pakistan and India. The first published inscribed seal appeared in 1875; most relevant objects belong to the Mature Harappan period.
Sortable year is the first published seal, not the Bronze Age inscription period. Harappa is one representative site in a transnational distribution.

Evidence in the record
Repeated sign positions and archaeological contexts support structural analysis. Scholarly studies propose links with trade, commodity control and administrative practice, but interpretation of function does not automatically assign phonetic values or translate a text.
Competing explanations
Official and research context
The reviewed studies analyse sign structure and possible administrative meaning; neither constitutes an agreed phonetic decipherment.
Conventional explanations
A language-encoding script, a system dominated by nonlinguistic notation, or mixed administrative conventions have been debated. Statistical regularity alone cannot decide between them. Claims identifying a modern language require independent, repeatable tests and a securely supported sign-reading method.
Arguments that remain contested
The system’s relationship to language and the meaning of individual inscriptions remain unresolved.
