Pronunciation
Forms
πλήθω (plḗthō) [1] Perfect with present sense πέπληθα, pluperfect ἐπεπλήθει; epic imperfect πλῆθε.[2][3][4]
Etymology
It is inherited from Proto-Hellenic *plḗtʰō,[1] from Proto-Indo-European *pleh₁- (“to fill, become full”).[1][5] The LIV reconstructs a present with the suffix *-dʰe-, *pléh₁-dʰe-, and compares Old Avestan frādat̰ (“furthers”).[5] Beekes, however, counts the ⟨θ⟩ of πλῆθος (plêthos), of this verb and of its perfect among presumably young Greek formations, like βρίθω (bríthō) beside βρῖθος (brîthos).[6] Πάπυρος describes the ending as a present suffix added to the stem of πίμπλημι (pímplēmi, “to fill”), as in νήθω (nḗthō) and πρήθω (prḗthō).[7]
The root is also in Latin pleō (“to fill”) and Sanskrit पिपर्ति (piparti, “fills”).[1][8]
Earliest recorded meaning
Homer uses it intransitively, to be full: of rivers in flood, of a river filled with corpses, of tables loaded with food, and of the full moon.[9][4][2]
Semantic evolution
In Archaic and Classical poetry it kept the sense “to be full”: Hesiod has barns full of food and a river swollen with winter rain, Aeschylus a sea full of wreckage and blood, and Pindar a thronging crowd in the market-place.[3][2][10] Sappho too speaks of the full moon.[2][3] In Attic prose it survived only in the phrase “when the agora is full”, that is, in the middle of the morning, used by Thucydides, Plato and Xenophon.[3][2]
Hellenistic poets used the old perfect πέπληθα with a present sense, as Theocritus of a spring brimming with water.[2][3] Only later poets, such as Oppian and Quintus of Smyrna, made it transitive, “to fill”.[2]
