Forms
ubī̆ (not comparable)[1] Varro has the spelling ube, and inscriptions ubei.[2]
Etymology
It is inherited from Proto-Italic *kʷuþei (“where”), built on the pronominal stem *kʷu- (“where”).[3][1] De Vaan notes that the form could reflect ⟨*kʷubʰei⟩, with the PIE instrumental ending ⟨*-bʰi⟩, or ⟨*kʷudʰei⟩, an Italic remodelling of ⟨*kʷu-dʰe⟩ “where”; the agreement with Indo-Iranian and Slavic makes the latter slightly more likely.[3] The initial ⟨c-⟩ was lost, but it survives in compounds such as alicubī and sīcubī; the final ⟨-ī⟩ was often shortened by iambic shortening.[1]
Cognate with Oscan puf (“where”), Umbrian pufe (“where”), Sanskrit कुह (kúha, “where”), Avestan kudā (“where”) and Old Church Slavonic къде (kŭde, “where, when”).[3][2]
Earliest recorded meaning
De Vaan dates it from Naevius;[3] Köbler lists the Twelve Tables.[4] Plautus has ubi patera nunc est? “where is the bowl now?”[2]
Semantic evolution
Ubi asks “where?” (ubi gentium? “where in the world?”), often in rhetorical questions implying that something is absent, and “in what situation?”; in colloquial Latin it also means “where to?”.[2] As a relative it means “where, in the place where”, often answered by ibi, “in which” of a situation, and colloquially it stands for a relative pronoun with a preposition, “in which, by which”.[2][1]
In time clauses it means “when, as soon as” (ubi prīmum), and as an indefinite adverb “anywhere, at any time”.[2]
