Etymology
It is the neuter of ultimus (“farthest, last”) used as a noun and an adverb.[1][2][3] De Vaan traces ⟨ultimus⟩ to Proto-Italic *oltamo- (“most to that side”) and Proto-Indo-European *h₂ol-tm̥Ho- (“furthest, last”), from the root of ille (“that”) (older ⟨olle⟩); cognate with Oscan últiumam (“last”).[4]
Earliest recorded meaning
Its first example in the OLD is Lucretius, where the sun has driven to the farthest parts of the sky (ultima caelī).[1][3]
Semantic evolution
As a noun it is the farthest part or end, as Cicero's heaven “which is the outermost and farthest part of the world”, and the last part or conclusion, as Livy's end of a speech and Seneca's “you have reached the end of human life”.[1] The plural ultima is the last things or the outcome, as Cicero's “wait for the end”, and a last resort, as Livy's men who decide to try the last resort.[1] Ad ultimum is “to the end, to the last” and “finally”, as in Livy and Quintilian.[1]
The adverbial ultimum is “for the last time”, as in Apuleius of a dead man “mourned for the last time”.[1][2]
