Etymology edit
From Proto-Italic *oktō, from Proto-Indo-European *oḱtṓw.
Cognates include Sanskrit अष्ट (aṣṭa), Ancient Greek ὀκτώ (oktṓ), Gothic 𐌰𐌷𐍄𐌰𐌿 (ahtau) and Old English eahta (English eight). Rubenbauer/Hofmann argue the form seems to stem from a PIE dual ("two times four fingertips" in a base-4 system).
Pronunciation edit
- (Classical) IPA(key): /ˈok.toː/, [ˈɔkt̪oː]

- c. 370 CE, Eutropius, Breviarium historiae romanae 2.2:
- T. etiam Quintius Cincinnatus Praenestinos, qui usque ad urbis Romae portas cum bello venerant, persecutus ad flumen Alliam vicit, octo civitates, quae sub ipsis agebant, Romanis adiunxit, ipsum Praeneste adgressus in deditionem accepit.
- Titus Quintius Cincinnatus, also, having pursued the Praenestini, who had advanced in a hostile manner to the very gates of Rome, defeated them on the river Allia, annexing eight cities that were under their dominion to the Roman empire; and, attacking Praeneste itself, forced it to surrender.
