Pronunciation

  • Classical: [ˈnãː][1]
  • Ecclesiastical: [ˈnam][1]

Forms

nam [1]

Etymology

It is inherited from Proto-Italic *nām, the accusative singular feminine of a pronominal stem ⟨*no-⟩ “that”, formed like tam and quam.[2][3][4][1] De Vaan and the TLL trace the stem to *h₂en- (“that”), found in Sanskrit अनेन (anéna, “by this”) and Old Church Slavonic онъ (onŭ, “he”); de Vaan also considers a link with the particle *ne (“like”).[3][4][1] The same stem may be in num and enim.[3][2]

Earliest recorded meaning

It is found from Livius Andronicus on.[3][5]

Semantic evolution

In early dialogue nam is assenting (“certainly, yes”); its main use is explanatory and causal, “for”, giving a reason or proof.[2][6] It also marks a transition (“again, moreover”), an exposition (“well then”), and in lively questions it is put before the interrogative (nam quamobrem? “why ever?”).[2] In prose it always begins the sentence.[6]

In Medieval Latin it could mean “on the other hand” or “but”.[7]

  • c. 550–1150 – Medieval Latin uses it for “but, on the other hand”.[7]
