Etymology and origin of the Latin word immo

Confidence
Uncertain
First attested
c. 235–200 BC, Naevius

Pronunciation

  • Classical: [ˈɪm.moː][1]
  • Ecclesiastical: [ˈim.mo][1]

Forms

immō (not comparable)[1] It is also spelled imō.[2][3][4] Plautus and Terence sometimes scan it as two short syllables.[2]

Etymology

The origin is uncertain.[5][2][6] An ablative ⟨*īmō⟩ of īmus “lowest, last” would suit the sense, but not the short first syllable and double ⟨m⟩, unless the negative force of the word caused the doubling, de Vaan asks.[5][1] He also notes that Hittite imma (“truly, indeed”) and Cuneiform Luwian imma look very similar, perhaps from Proto-Indo-European *im and a form ⟨*moh₂⟩ or ⟨*moh₁⟩, but that a geminate ⟨*-mm-⟩ would not be expected to survive in Latin.[5][1] Others have proposed ⟨*ipsimō⟩, from ipse.[1] Lewis and Short took it as a superlative of in, like summus and prīmus.[3]

Earliest recorded meaning

De Vaan dates it from Naevius.[5] Plautus has fēcistī ut tibi … numquam referre grātiam possim satis – immō potes, “you have made it impossible for me ever to repay you enough” – “on the contrary, you can”.[2]

Semantic evolution

Immō corrects what has just been said: it denies it outright (“on the contrary, no”), or corrects it by going further (“nay rather, what is more”, often with vērō, potius, edepol or hercle).[2][3][1] It introduces an order to do something different, and in immō sī sciās “if only you knew” it implies the other person spoke in ignorance.[2] The TLL notes that it is very common in Plautus and Terence.[7]

Church Latin glosses it “on the contrary”, either “yes indeed” or “no indeed”.[4]

Timeline

  • c. 235–200 BC – Used by Naevius.[5][6]
  • c. 250–184 BC – Plautus: immō potes.[2][6]
  • 190–159 BC – Terence uses it often.[7][6]
  • 81/79–52/50 BC – Catullus uses it in a pentameter.[7][6]
