Reconstruction

The adverb and preverb is *upó 'under' in Beekes,[1] *upo 'below' in Fortson,[2] and *up-o in Kloekhorst and Pronk, who segment it as a stem with a petrified ending *-o.[3] Dictionaries differ on the onset: de Vaan writes *(h1)upo 'up, from below',[4] Kroonen *h₁up-o,[5] EWAia *(h)upo with the laryngeal marked as uncertain,[6] and Adams *(s)h₄upo 'under, below'.[7] Dunkel argues against any initial laryngeal, since a form with a laryngeal would have been vocalised differently in Greek.[8] Ringe tentatively sets up *supó 'under, near', which he thinks became *upó under the influence of *upér 'over'.[9]

Morphology

Kroonen and Beekes take the final *-o as a petrified allative ending, the same as in *pró and the particle for 'away'.[5][10] Kloekhorst and Pronk set this petrified *-o of *pr-o and *up-o 'down to' beside the allative ending -a of Hittite, which also continues *-o.[3] For Dunkel the base is a locative particle *up 'above', from which *up-o was the directive form 'upwards' and *upér the locative adverb; unextended *up and *up-o were at first preverbs only.[11]

Evidence

The particle is found in Indo-Iranian, Greek, Italic, Celtic and Germanic, with a cognate in Tocharian if the sibilant form is accepted.[12][7] In Anatolian, Sturtevant connected Hittite up- (“to rise, of heavenly bodies”) with the full grade of this particle.[13] Latin and Greek point to an initial s, which Beekes and Chantraine call obscure,[12][14] while de Vaan takes the Celtic forms as showing that the s- of Latin is an Italic development.[4]

Competing analyses

Dunkel separates two rhyming antonyms that most handbooks merge: *up 'above' with directive *up-o 'upwards', and *sup 'below' with directive *sup-o 'downwards'.[15] He rejects both an s-mobile and a vague meaning as the reason for merging them.[15] On his account Indo-Iranian, Germanic and Armenian continue only *up, Tocharian only *sup-o, and Greek, Italic and Celtic cannot decide, since the two fell together there by parallel but opposite levellings.[15] Watkins took Hittite forms with and without s- as proof that the two were one particle, which Dunkel denies.[15] Ringe also starts from a form with an initial s, but derives the s-less form from it.[9]

Meanings

  1. under, below,[1][2] under, near[9]
  2. up, from below,[4] upwards[8]

Chantraine notes that 'under' is well attested in Greek, Italic, Gothic and Celtic, and that a sense 'from below' may have led to the Indo-Iranian meanings 'towards, beyond, on'.[14] Dunkel describes the Vedic adverb as mostly horizontal, 'near to, towards', and calls the Gothic sense 'under' a Gothic reversal of meaning.[16]

Derivatives

  • The superlative *(h1)up-m(H)o- 'highest', in Sanskrit उपम (upamá, “uppermost, highest”)[17] and Latin summus (“highest”).[18][19] Ancient Greek ὕπατος (húpatos) replaced the suffix with -το-.[19]
  • Ancient Greek ὕπτιος (húptios, “bent backwards, supine”), formed with the suffix -tio-.[20]
  • Latin supīnus (“lying face upwards”), which de Vaan takes as keeping the old sense 'upwards'.[4]
  • *up-s 'above, upwards', with Ancient Greek ὕψι (húpsi, “on high”) and Latin sus- (“up”).[21]
  • Proto-Germanic *eup ~ *upp, cited by Kroonen beside *uba,[5] and English up from *up-n- in Beekes.[1]
  • The locative adverb *upér 'over'.[8]

Reflexes

  • Indo-Aryan: Sanskrit उप (úpa, “towards, near to, at”).[17][6]
  • Iranian: Avestan upa (“towards, near, at”), Old Persian upā (“at, by”).[6]
  • Greek: Ancient Greek ὑπό (hupó, “under, underneath, from under”), Mycenaean Greek u-po.[12]
  • Italic: Latin sub (“under, below; reaching from below, up to”), Umbrian su (“under”).[4]
  • Celtic: Proto-Celtic *ufo- (“under”), Old Irish fo (“under”).[22]
  • Germanic: Proto-Germanic *uba (“under; above”), Gothic 𐌿𐍆 (uf, “under”), Old Norse of (“over; about”), Old High German oba (“above, on, over”).[5]
  • Tocharian: Tocharian B spe (“near by”), if from a form with an initial s.[7]
