Impression of an Indus stamp seal, showing a string of five "Indus script" symbols; the Indus script is interpreted by some scholars as the writing system of the Harappan language.

The Harappan language is the unknown language or languages of the Bronze Age (c. 2nd millennium BC) Harappan civilization (Indus Valley civilization, or IVC). The Harappan script has long defied attempts to read it, and therefore the language remains unknown.[3] The language being unattested in any readable contemporary source, hypotheses regarding its nature are reduced to purported loanwords and substratum influence, the substratum in Vedic Sanskrit and a few terms recorded in Sumerian cuneiform (such as Meluhha), in conjunction with analyses of the undeciphered Indus script.

There are a handful of possible loanwords from the language of the Indus Valley civilization. Sumerian Meluhha may be derived from a native term for the Indus Valley civilization, also reflected in Sanskrit mleccha meaning non-Vedic or native, and Witzel (2000) further suggests that Sumerian GIŠšimmar (a type of tree) may be cognate to Rigvedic śimbala and śalmali (also names of trees).[4]


There are a number of hypotheses as to the nature of this unknown language:

Hypotheses that have gained less mainstream academic acceptance include:

Multiple languages

The Indus script only indicates that it was used to write one language (if any), but it is quite possible that multiple languages were spoken in the IVC, much as Sumerian and Akkadian co-existed in Mesopotamia for centuries. Jane R. McIntosh suggests one such possibility: Para-Munda was originally the main language of the civilization, especially in the Punjab region. Later, the proto-Dravidian immigrants introduced their language to the area in the 5th millennium BC. The Dravidian language was spoken by the new settlers in the southern plains, while Para-Munda remained the main language of those in Punjab.[11]

Other theories

Michael Witzel suggested as an alternative, that an underlying, prefixing language similar to Austroasiatic, notably Khasi; he called it "para-Munda" (i.e. a language related to the Munda subgroup or other Austroasiatic languages, but not strictly descended from the last common predecessor of the contemporary Munda family). Witzel argued that the Rigveda showed signs of this hypothetical Harappan influence in the earliest historic level, and Dravidian only in later levels, suggesting that speakers of Austroasiatic were the original inhabitants of Punjab and that the Indo-Aryans encountered Dravidian speakers only in later times.[12][13] The theory was since further supported by Franklin Southworth.[citation needed]

As of 2019, Witzel prefers to leave the question of the original Indian language(s) open until better reconstructions for Dravidian and Munda substrate components in Indo-Aryan languages have been done.[14]
