Etymology

It is inherited from Proto-Italic *enim, the accusative singular of *eno- (“that one”), inherited from Proto-Indo-European *h₁e-no-.[2][1] The OLD likewise sees a pronominal stem ⟨*(e)no-⟩, as in nam and nunc, with the ending ⟨-im⟩.[3] Pokorny derived it from the stem of Lithuanian anàs (“that”) and Old Church Slavonic онъ (onŭ, “he”), but de Vaan reconstructs that pronoun as *h₂en- and assumes that the initial /e/ was taken from the pronoun of is.[2]

Cognate with Oscan ínim (“and”) and Umbrian enem (“and”), which in Umbrian joins only sentences.[2][3]

Earliest recorded meaning

It is found from Naevius on;[2] Plautus uses it often in dialogue.[3][4]

Semantic evolution

In early dialogue enim is an affirming particle: “well!”, “why!”, “of course!” at the start of a reply.[3] Its classical use is causal and explanatory: “for”, “namely”, neque enim “for … not”, giving the reason for what has just been said.[3][5] It normally stands second in its sentence.[3]

Medieval Latin also used it for “but, now”.[6]

Timeline

  • c. 235–200 BC – First found in Naevius.[2]
  • c. 250–184 BC – Plautus uses it to underline an answer: quia enim mē adflīctat amor.[3][4]
  • 70–19 BC – Virgil uses it to stress the preceding word.[3][4]
  • c. 550–1150 – Medieval Latin uses it for “but, now”.[6]
