Etymology and origin of the Latin word Aprilis
- Confidence
- Disputed
- First attested
- 116–27 BC, Varro
Forms
Aprīlis (neuter Aprīle); third-declension two-termination adjective[1] As a noun, Aprīlis, -is m., the month of April.[2][1] Medieval Latin also has Aprilius, -ī m.[3]
Etymology
The origin is uncertain.[2][4][5] De Vaan notes that April was the second month of the Roman year and connects it, with hesitation, with ab (“away from”), as *ap(e)rīlis (“the following, the next”), from Proto-Italic *ap(e)ro- and ultimately Proto-Indo-European *h₂epo (“away from, off”).[5] This could reflect the same form *ap(e)ri- (“openness”) that he posits for aprīcus (“sunny”).[5] Neri starts instead from *h₁p-r-, a form of *h₁(e)p(-i) (“toward”).[5] The ending ⟨-īlis⟩ may follow the month names Quīntīlis and Sextīlis.[5][6]
The OLD calls the origin doubtful and perhaps Etruscan,[2] and Wiktionary bases it on Etruscan 𐌖𐌓𐌐𐌀 (apru), a borrowing of Ancient Greek Ἀφροδίτη (Aphrodítē, “Venus”).[1][6]
Ancient scholars gave both explanations: Varro reports that Fulvius and Iunius named the month after Venus, but he himself preferred aperiō (“to open”), because spring opens everything,[4][2] and Isidore gives both.[7]
Earliest recorded meaning
Its first author is Varro, explaining the name of the second month: magis putō dictum, quod vēr omnia aperit, Aprīlem, “I rather think April was so called because spring opens everything”.[2][5][8]
Semantic evolution
It was first an adjective agreeing with mēnsis, Kalendae, Nōnae or Īdūs: Cicero dates a letter Nōnīs Aprīlibus, “on the Nones of April”.[2][9] Horace calls the month that of sea-born Venus,[2] and Ovid uses Aprīlis alone as a noun.[2][10] Tacitus reports that the month was to take Nero's name.[2]
The month name lived on in nearly every branch of Romance: DÉRom reconstructs Proto-Romance */aˈpril-e/, the source of Sardinian apríle, Romanian prier and Italian aprile, and a derivative */aˈpril-i-u/ beside it.[10] Old English Aprelis and Old High German abrello were taken from it,[11] and English April came through Old French avril around 1300.[6]
