The Weaver’s Thread in the Lexicon: What Austroasiatic Loanwords in Early Indo-Aryan Reveal About Ancient Textile Technology

Language preserves traces of human contact that material artifacts alone cannot fully capture (Swaveda). When speaker communities meet, they exchange tools, crop varieties, and manufacturing techniques (Swaveda). They also exchange words (Swaveda). In the early texts of Old Indo-Aryan (the ancient ancestor of Indo-Aryan languages like Sanskrit), historical linguists have tracked a layer of foreign vocabulary that points to intimate interactions between incoming pastoralist groups and established South Asian speech communities (Swaveda).

The Sanskrit word karpāsa (cotton) appears in late Vedic and classical texts (Swaveda). It lacks an Indo-European pedigree (Swaveda). Historical linguists trace karpāsa to an Austroasiatic root preserved across modern Austroasiatic and Munda languages (a branch of the Austroasiatic language family spoken in central and eastern India) (Swaveda). In comparative linguistics, this structural loanword serves as a fossilized record of a technological handover (Swaveda).

Tracing the Substrate Layer

The earliest layer of Indian literature, the Rigveda, contains hundreds of terms that cannot be reconstructed to Proto-Indo-European roots (Swaveda). Michael Witzel, an Indologist at Harvard University, has documented how substrate influences—features imported from local, non-Indo-European speech communities—shaped Old Indo-Aryan (Swaveda).

These non-Indo-European terms cluster heavily in specific domains: local flora, agricultural practices, and textile processing (Swaveda). Evidence shows that these words entered Indo-Aryan during periods of sustained bilingualism (Swaveda). When a incoming population adopts an entire vocabulary for a craft or crop, it indicates that the local community possessed established technical expertise (Swaveda).

In his analyses, the linguist Franklin Southworth identified Austroasiatic sources for several early South Asian agricultural terms (The Quest for the Origins of Vedic Culture). Along with karpāsa (cotton), botanical terms like tāla (palmyra palm), tāmbūla (betel nut), and kadalī (banana) feature prefixes and phonetic shapes characteristic of Austroasiatic morphologies (The Quest for the Origins of Vedic Culture).

Cotton in the Material Record

Archaeobotanical evidence confirms that cotton (Gossypium) processing existed in South Asia millennia before the arrival of Indo-Aryan speakers (ResearchGate).

Evidence shows that the earliest preserved cotton fibers in South Asia were found at Mehrgarh in modern Pakistan (ResearchGate). In 2002, a research team led by Christophe Moulherat published findings in the Journal of Archaeological Science analyzing mineralized cotton threads recovered from copper beads in a Neolithic burial at Mehrgarh (Oko Farms). These fibers confirm that local populations spun and utilized cotton thread by the sixth millennium BCE (ResearchGate).

By the Bronze Age, the Indus Valley Civilization engaged in widespread cultivation of Gossypium arboreum, the native South Asian cotton species (Harappa). Excavations at sites like Mohenjo-daro and Harappa have yielded terracota spindle whorls, woven textile impressions preserved on clay vessels, and dyed thread fragments (Harappa).

When Indo-Aryan pastoralists encountered established agricultural communities in northern South Asia, they adopted the existing technological vocabulary (Swaveda). The term karpāsa reflects this exchange (Swaveda). The Austroasiatic prefix ka- (seen in terms related to plant matter and local wildlife) combined with the base root to enter Sanskrit as a fully acclimatized loanword (Reddit).

The Geographic and Linguistic Debate

Scholars debate the exact geographic mechanics of this contact (Swaveda).

Michael Witzel proposed a hypothesis involving a "Para-Munda" language—an extinct northwestern branch of Austroasiatic spoken in the Punjab and surrounding regions prior to or alongside the early Vedic period (Reddit). Under this framework, Austroasiatic-speaking communities were present across northern India, allowing direct, local contact between Indo-Aryan and Austroasiatic groups (Swaveda).

Other historical linguists argue for a more eastern concentration of Austroasiatic languages (Swaveda). Scholars like Paul Sidwell argue that Austroasiatic languages expanded into South Asia from Southeast Asia via eastern India (The Oxford Handbook of Early Southeast Asia). Under this model, botanical loanwords like karpāsa and tāla filtered westward through trade networks and regional exchanges, rather than through direct geographic overlap in the far northwest (Swaveda).

Despite these debates over geography, the lexical evidence consistently shows that Old Indo-Aryan absorbed terms for specialized local flora and fiber technologies from indigenous non-Indo-European languages (Swaveda).

A Global Linguistic Voyage

Once karpāsa was integrated into Sanskrit, the word traveled well beyond the Indian subcontinent (Mother India).

As South Asian cotton textiles were traded across the ancient Mediterranean and Near East, the name followed the commodity (Mother India). Classical Hebrew borrowed the term as karpas (fine linen or cotton cloth), appearing in the Book of Esther (Mother India). Ancient Greek adopted it as karpasos, which passed into Latin as carbasus, referring to fine cotton fabric or sails (Mother India).

This lexical chain demonstrates how technical knowledge and botanical products move together across civilizations (Swaveda). Long before South Asian cotton became a global trade staple, the vocabulary for processing it was forged through the intermingling of Austroasiatic and Indo-Aryan speech communities within India (Swaveda).
