Pronunciation

  • 5th-century BC Attic: /sɛ̌ː.pɔː/[1]
  • 4th-century AD Koine: /ˈsi.po/[1]
  • 10th-century Byzantine: /ˈsi.po/[1]

Forms

σήπω (sḗpō) [1] Doric σάπομαι (Bacchylides); perfect σέσηπα with passive sense, aorist passive ἐσάπην, future σαπήσομαι; the active future σήψω and aorist σῆψαι are rare.[2][3][4]

Etymology

The origin is unclear.[3][2] Frisk held it to be an inherited word because of its structure, though isolated in Indo-European.[5] The alternation of the stem ⟨σηπ-⟩ with ⟨σαπ-⟩ (as in σαπρός (saprós, “rotten”)) has been taken as a sign of Indo-European origin, and LIV reconstructs a root Proto-Indo-European *Kyeh₂p- (“to rot”); but Beekes notes that no cognates are known and that a zero grade of such a root would not give the adjective, so the verb may be Pre-Greek.[2][1] The old comparisons with Sanskrit क्याकु (kyāku, “mushroom”) and Lithuanian šiùpti (“to putrefy”) are rejected by Beekes and Chantraine.[2][3]

Earliest recorded meaning

In Homer it occurs in the perfect and the passive, meaning “rot”: the ship timbers of the Achaeans have rotted after nine years at Troy, and Hector's body does not rot.[6][4]

Semantic evolution

In Herodotus the passive is used of dead bodies and of a wounded thigh that mortifies.[4][7] The active "make rotten" appears in Aeschylus, of a viper's poison,[4][7] and Plato uses it figuratively: idleness and stillness rot and destroy.[4][7] An Athenian inscription of the 5th century BC uses it of soaking hides, and the Hippocratic writers of bringing a sore to suppuration.[4]

The verb gave σῆψις (sêpsis, “putrefaction”), σηπεδών (sēpedṓn, “decay”) and σηπτικός (sēptikós, “causing rot”).[2][5] In medieval vernacular Greek it lived on beside new presents built on the aorist, such as σαπαίνω (sapaíno).[8] Modern Greek keeps the middle σήπομαι (sípome) only as a learned word for "rot".[9]
