Pronunciation

Forms

ultrō (not comparable)[1]

Etymology

It is from the ablative singular of Proto-Italic *olteros, the source of ⟨ulter⟩, like ultrā.[1][2] De Vaan traces the stem ⟨*ultero-⟩ “more to that side” to Proto-Indo-European *h₂ol-tero- (“further”), as in ulterior and ultimus.[3]

Earliest recorded meaning

The OLD's earliest citations are from Plautus, such as ultrō istum ā mē! “away with him!”.[2][4] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

Its first sense was to a point farther off, away, in exclamations, as in Plautus, ultrō citrōque meant to and fro, as in Cato and Cicero.[2][6] From “beyond” it came to mean in addition, into the bargain; the reverse of what might be expected, even, actually; and above all of one's own accord, on one's own initiative, unprompted, as in Plautus and Virgil.[2][6]

In Ecclesiastical Latin it meant spontaneously, voluntarily, beyond, besides.[7] British Medieval Latin used it for away, and ultrō citrōque back and forth.[8]
