Evidence guide
What Language Did Mohenjo-daro Speak?
Nobody can presently name the language spoken in Mohenjo-daro’s streets. The city’s inscriptions are short, mostly on seals, and they have no accepted reading. Proto-Dravidian, Indo-Aryan, isolate and mixed-register models are all open.
Research compilation from a published ICIT-style digitization — not a complete or licensed photographic corpus
Key takeaways
- A city can be multilingual.
- Seals are a narrow register.
- Do not confuse a famous site with a solved language.
Direct answer
We do not know what language Mohenjo-daro spoke. Anyone who states a single family as fact is ahead of the evidence.
What the site actually gives us
A large excavated city, many seals, some tablets and copper objects, and a demonstration-heavy share of published inscriptions. Excavation intensity can make Mohenjo-daro look statistically dominant.
How to read claims
A Proto-Dravidian proposal about a fish-like sign is a semantic candidate. An Indo-Aryan mapping of the same sign is another. Neither is a voice recording of the lower town.
What remains uncertain
- Household speech versus administrative marking.
- Whether the city’s writing matches its speech.
