Etymology

It is inherited from Proto-Italic *an, perhaps from Proto-Indo-European *h₂en (“there, on the other side”).[2][1] De Vaan compares Gothic 𐌰𐌽 (an, “so? now?”), Lithuanian angu (“or”) and Old Prussian anga-anga (“whether”); the link with the Greek particle Ancient Greek ἄν (án), which the OLD gives, is less certain.[2][3] Lewis & Short call the origin very obscure, and the TLL suggests a contraction of ⟨*atne⟩.[4][5]

Earliest recorded meaning

It is found from Livius Andronicus on: inferus an superus tibī fert deus fūnera, Ulixēs? “is it a god below or above who brings you death, Ulysses?”.[2][3]

Semantic evolution

An introduces the second part of a double question (“or”), with or without utrum or -ne in the first; alone it opens a question with surprise or indignation (“can it really be that …?”), or offers a suggested answer.[3][1] In indirect questions it means “whether” (an nōn “or not”), and haud sciō an or nesciō an means “I rather think, probably”.[3][4]

From the Augustan period it can stand for sīve; in Medieval Latin it was a plain synonym of aut and vel.[1][6]

Timeline

  • 204–169 BC – Ennius: vīvam an moriar, “whether I live or die”.[3][7]
  • 81–43 BC – Cicero: paucīs ante quam mortuus est diēbus an mēnsibus, “a few days or months before his death”.[3][7]
  • c. 550–1150 – Medieval Latin uses it as a synonym of aut.[6]
