   rare and archaic: an exclamation of joy, triumph, celebration, or ritual invocation

   The old poem commands its singers to cry, "Io! Paean! Io!"

Borrowed from Latin io, an exclamation of joy or triumph; compare Ancient Greek io, a cry of invocation or exultation. In English it survives chiefly in archaic and literary formulas such as Io Paean. This interjection is distinct from the name Io and the abbreviation I/O.
