Etymology and origin of the Proto-Indo-European word *wed-
- Confidence
- Probable
Reconstruction
LIV writes the root *u̯ed- 'to gush forth, to well up',[1] and NIL sets up the same verb but marks it as a questionable root.[2] Smoczyński has *u̯ed- 'to gush, of water; to wet',[3] and Kroonen refers to the root as *wed- 'to be wet'.[4]
Morphology
The only verb LIV reconstructs is a nasal-infix present *u-né/n-d-, in Vedic उनत्ति (unátti, “moistens”), with factitive meaning; the Atharvavedic perfect Sanskrit ऊदुः (ūdur) is an innovation.[1] LIV suggests that traces of the nasal present may survive in nouns such as Latin unda (“wave”) and Old Prussian unds (“water”),[1] and Weiss reports that some scholars derive the n of unda and Lithuanian vanduõ from it.[5] Kroonen rejects this, deriving unda from *ud-neh₂-,[4] and Derksen derives the Balto-Slavic nasal from a suffix.[6]
Evidence
As a verb the root survives only in Indo-Iranian, but the noun *u̯ód-r̥ 'water' is widespread.[1] Its derivatives are cited below from Anatolian, Indo-Iranian, Greek, Italic, Germanic, Slavic, Baltic, Armenian and Tocharian.[7][6][8][9]
Competing analyses
Kloekhorst reports that it is disputed whether the root of Hittite utnē (“land”) and Armenian գետին (getin, “ground”) is the same as that of 'water', and that a connection with Greek οὖδας (oûdas, “ground”) would require *h₃ued-.[10] Kroonen, following Lubotsky, derives a root *ueH- 'water' from *ued-, since *-dr regularly became *-h₁r in early PIE.[11]
The root 'to speak' is a different one, *h₂u̯ed- in Kölligan's lexicon of PIE, *h₂wed-.[12]
Meanings
In Vedic the nasal present is factitive, 'to moisten', and intransitive only once in the Rigveda.[1]
Derivatives
- *u̯ód-r̥, *ud-én- 'water', *wódr̥.[7][1]
