Etymology and origin of the Proto-Indo-European word *bʰuH-

Reconstruction

Clackson, Fortson and Ringe write the root *bʰuH- or *bhuH-, Ringe adding *bhuh₂- with a query.[1][2][3] LIV sets it up as *bʰu̯eh₂- "to grow, arise, become".[4] The Leiden dictionaries assume a root *bʰh₂u- with metathesis: Beekes derives *bhuh₂- from *bhh₂u-, de Vaan reconstructs the aorist *bh(e)h2u-, Kroonen *bʰéh₂u- and Derksen *bʰHu-.[5][6][7][8] Schrijver argues for *bhHu- rather than *bhuH-.[9]

Morphology

Clackson and Ringe present it as a root that does not ablaut.[1][3] LIV notes that its full grade II rests almost only on Old Latin fuās (“may you be”) and the Italic imperfect suffix, the zero grade having been generalised nearly everywhere.[4] LIV reconstructs a root aorist in Vedic अभूत् (ábhūt, “has become”) and Greek ἔφῡν (éphūn, “grew, became”), a thematic present *bʰéu̯h₂-e- in Sanskrit भवति (bhávati, “becomes, is”), a zero-grade present *bʰuh₂-i̯é- in Latin fīō (“to become”), a perfect, and a doubtful s-desiderative.[4] Beekes says the whole Greek verb is built on the intransitive aorist ἔφῡν.[5] Kroonen explains Germanic *būan- beside *bōan- from an ablauting root present *bʰéh₂u-ti, plural *bʰh₂u-énti.[7]

Evidence

Clackson says the root survives in every branch except Anatolian and Tocharian.[1] In Italic it gave the imperfect suffix *-f-, and in Slavic the infinitive and aorist stem of "to be".[2][10]

Meanings

  1. to grow, to arise, to become[4]

Sihler notes that in the Rigveda the aorist Sanskrit अभूत् (ábhūt) usually means "became" rather than "was".[11] Germanic developed "to dwell", in Gothic 𐌱𐌰𐌿𐌰𐌽 (bauan, “to dwell”).[7]

Derivatives

  • Ancient Greek φυτόν (phutón, “plant”) and Old Irish both (“cabin”), from *bhh₂u-to-.[5]
  • Ancient Greek φῦμα (phûma), matching Sanskrit भूमन् (bhū́man-, “earth, world, being”).[5]
  • The past participle *bhh₂u-tó- in Latin futūrus (“about to be”).[6]

Reflexes

  • Indo-Aryan: Sanskrit भवति (bhávati, “becomes, is”), listed by LIV.[4]
  • Greek: Ancient Greek φύομαι (phúomai, “to grow, arise, become”).[5]
  • Italic: Latin fuī (“I was”).[6]
  • Germanic: Proto-Germanic *būaną (“to live, dwell”).[7]
  • Baltic: Lithuanian būti (“to be”).[12]
  • Slavic: Old Church Slavonic бꙑти (byti, “to be”).[8]
