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

Confidence
Established

Reconstruction

The root is *spek̑- "to look, watch, spy" in LIV,[1] and *speḱ- in de Vaan and Beekes.[2][3] Greek shows a metathesis of the initial sp- and the final k.[1][3]

Morphology

LIV reconstructs a full-grade i̯e-present *spék̑-i̯e-, an s-aorist *spḗk̑/spék̑-s- and an iterative *spok̑-éi̯e-, and with question marks an i-reduplicated present and a néu̯-present; the Vedic perfect is an innovation.[1] The present may also be *spek̑-i̯é-, the Vedic root accent being perhaps secondary.[1] De Vaan sets up the present *speḱ-ie/o-, the aorist *speḱ-s- and a root noun *speḱ- "who sees".[2]

Evidence

Reflexes are cited below from Indo-Aryan, Greek, Italic and Germanic.[1][3] Beekes equates Greek σκέπτομαι (sképtomai), Latin speciō, Avestan spasiieiti and Sanskrit पश्यति (páśyati),[4] and the s-aorists of the three languages with one another.[3] Vedic páśyati, which lost its s-, serves as the present of the root "to see" from *derḱ-.[1]

Meanings

  1. to look, to watch, to spy[1]

Kölligan describes the root as the PIE verb of "spying", beside *derḱ- and other verbs of seeing.[5] Beekes compares a Vedic formula calling the sun a spy with the Homeric one calling Helios a Ancient Greek σκοπός (skopós).[3]

Derivatives

  • The root noun *spék̑- "watcher", in Indo-Iranian words for "spy" and in Latin haruspex.[1]
  • *spóḱ-eh₂, in Greek σκοπή (skopḗ) and Old Norse spá (“prophecy”).[3]
  • *spek-tlo-, probably in Latin speculum.[2]

Reflexes

  • Indo-Aryan: Sanskrit पश्यति (páśyati, “sees”).[4]
  • Greek: Ancient Greek σκέπτομαι (sképtomai, “to look about, consider”).[3]
  • Italic: Latin speciō (“to look at”).[2]
  • Germanic: Old High German spehōn (“to spy”), a denominative, cited by LIV.[1]
