Etymology

The TLL calls its origin uncertain.[2] The OLD derives it from āctus “act”, like ⟨astūtus⟩ from ⟨astū⟩, and Wiktionary gives either the adverbial accusative of an unattested ⟨*āctūtus⟩, or a fusion of ⟨āctū⟩ and tum “then”, as Corssen suggested.[3][1][4]

Earliest recorded meaning

Its earliest source is Plautus, and Terence, Livy and Quintilian also use it.[5][6] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It meant forthwith, immediately, without delay.[3][6]

British Medieval Latin used it for immediately, as in Aldhelm.[7]

Timeline

  • c. 250–184 BC – Plautus uses it.[5][6]
  • 59 BC–17 AD – Livy uses it.[6][5]
