Pronunciation

  • IPA (Classical): [ˈa.lɪ.biː][1]
  • IPA (Ecclesiastical): [ˈaː.li.bi][1]

Forms

alibī (not comparable)[1]

Etymology

It is from Latin alius (“other”) + ibī (“there”).[1][2][3] The OLD analyses it as alius with the ending -bi of ubī.[4] Lewis & Short take it as a contraction of aliubī.[5]

Earliest recorded meaning

Naevius, in a comic fragment, contrasts one hand busy in one place with a foot tripped elsewhere, and Plautus uses it often.[4] Köbler dates Naevius about 235–200 BC.[3]

Semantic evolution

It meant in another place, elsewhere.[4] Cicero uses it of another passage of a book, and Plautus and Terence of another matter or in other respects.[4][6] Lewis & Short note that it was rare in Cicero and the poets but very frequent after Augustus, especially in Pliny.[5] In medieval Latin it also meant “here … there”, “partly … partly”, and “to another place”.[7][3]

English alibi, a plea of having been elsewhere when a crime was committed, was borrowed from the adverb in 1743.[8]
