Pronunciation

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

Forms

σήμερον (sḗmeron) [1] Attic τήμερον (tḗmeron), also τήμερα (tḗmera) in a fragment of Aristophanes.[2] Doric σάμερον (sámeron).[2][3]

Etymology

It goes back to *κιάμερον (kiámeron), a univerbation from Ancient Greek κι- (ki-, “this, here”) + ἡμέρα (hēmérā, “day”), perhaps through an adjective meaning “belonging to this day”.[3][4] The first part is the pronominal stem of ἐκεῖ (ekeî, “there”), from Proto-Indo-European *ḱi- (“this”),[3][5] and the word took the neuter gender as αὔριον (aúrion, “tomorrow”) did.[5] Ionic has /s/ where Attic has /t/, and the word stands to ἡμέρα (hēmérā) as σῆτες (sêtes, “this year”), Attic τῆτες (têtes), stands to ἔτος (étos, “year”).[2] Chantraine thinks that the Attic form served as the model for that word.[5] LSJ compares Lithuanian šis (“this”) and Latin citra, and Wiktionary cis and hic.[2][1]

Earliest recorded meaning

In Homer it means “today” and “for today”: Zeus grants glory to a warrior today, and the gods agree to stop the fighting for the day.[6][2]

Semantic evolution

Pindar has the Doric form, and Attic writers from Cratinus and Aristophanes on use τήμερον (tḗmeron), which the 2nd-century Atticist Moeris recommends, although comedy sometimes has the Ionic form.[2] With the article it makes phrases such as “this very day” (Demosthenes) and “for today” (Plato).[2] Its adjective σημερινός (sēmerinós) “of today” is first found in Callimachus.[3]

Hellenistic Greek used only the Ionic form: it is in the papyri from the 3rd century BC, and the Attic one never occurs in the New Testament, where “today” and “this very day” are frequent, as in the Lord's Prayer.[2][7]

Medieval vernacular Greek had σήμερο (símero) and σήμμερον (símmeron) beside it.[8] The Modern Greek word is σήμερα (símera), whose ending was remade after τώρα (tóra, “now”).[9][10] The old form lives on as a learned word, mostly in the phrase “on this day”.[9]
