Forms

at [1]

Etymology

It is inherited from Proto-Italic *ati, inherited from Proto-Indo-European *h₂et(i) (“back, away”); the final /t/ goes back to Proto-Italic ⟨*-ti⟩.[2][1] The old prefix use survives in atavus (“great-great-great-grandfather”).[2]

Cognate with Ancient Greek ἀτάρ (atár, “but, nevertheless”), Old Irish aith- (“again”), Lithuanian at- (“back”), Old Church Slavonic отъ (otŭ, “from”) and Gothic 𐌰𐌸𐌸𐌰𐌽 (aþþan, “but”).[2][3][4] De Vaan notes that it is not fully clear which cognates belong to ⟨at⟩ and which to et.[2]

Earliest recorded meaning

It is found from Plautus on.[2]

Semantic evolution

At marks a contrast between persons or things (“but, on the other hand”), a change of subject in narrative (“now, meanwhile”), and a contrast with what precedes.[4][5] Alone or with enim it introduces an objection (“but, you will say”).[4] At tamen “but yet” is often written as one word.[4]

The form ast is also found.[5][3]

Timeline

  • c. 250–184 BC – First found in Plautus.[2]
  • 204–169 BC – Ennius: at Rōmulus pulcher …, contrasting Romulus with Remus.[4][6]
