Pronunciation

  • IPA (Classical): [ˈtʊŋk][1]
  • IPA (Ecclesiastical): [ˈtuŋk][1]

Forms

tunc (not comparable)[1]

Etymology

It is formed from tum “then” and the deictic particle -ce, Old Latin ⟨*tunce⟩, like nunc “now”.[2][3][1][4] ⟨Tum⟩ continues Proto-Indo-European *tóm, the accusative of the demonstrative ⟨*só⟩.[4]

Earliest recorded meaning

Köbler dates it from Livius Andronicus;[5] Plautus has nam tunc dentēs mihi cadēbant prīmulum, “for then my teeth were first falling out”.[2]

Semantic evolution

Tunc means “then, at that time”, in the past, the future or in general, and in a supposed case “in that event”.[2][1] Iam tunc is “already then”.[2] In early and classical Latin it is more emphatic than tum, especially against nunc or answering a cum clause; in Augustan verse it is used mainly before a vowel, and in later Latin the two words are hardly distinguished.[2][3]

In New Latin it also means “therefore”.[1] Church Latin has ex tunc “from of old”.[6]
