Forms

atque [1]

Etymology

It is a compound with the enclitic -que “and”, but the first part is disputed.[2][1] De Vaan thinks from Latin at + -que more likely, since a compound with ad would be expected to keep or restore ⟨ad⟩; the TLL also sees ⟨at⟩ rather than ⟨ad⟩ in it.[2][3] The OLD derives it from ⟨ad-⟩ and ⟨-que⟩, and Dunkel's interpretation as *ad-kʷe, based on a line of Ennius in which the doubled conjunction means “nearer and nearer”, is called not implausible by de Vaan.[4][2] The comparison with Umbrian ape (“when, as soon as”) is uncertain because the meanings differ.[2][1]

The short form ac stands mostly before consonants.[2][4]

Earliest recorded meaning

It is found from Livius Andronicus on.[2][5]

Semantic evolution

Atque adds a more particular or emphatic term (“and also, and what is more”), opens an emphatic sentence (“and indeed”), introduces a fresh point, and corrects or strengthens what precedes (atque adeō “and in fact”, ac potius “or rather”).[4] After words of likeness and difference it means “as, than” (aliter atque “otherwise than”).[1][6][7]

Döderlein notes that atque and ac join near-synonyms, unlike et and -que.[8] In British Medieval Latin it was less common than in Classical Latin, and ac was no longer limited to consonants.[9]

Timeline

  • c. 280–200 BC – First found in Livius Andronicus.[2][5]
  • c. 250–184 BC – Plautus uses it to announce someone just mentioned: atque eccum ipsum hominem “and look, here's the man himself”.[4][5]
  • 81–43 BC – Cicero uses atque adeō to correct and strengthen a term.[4][5]
