The word octave derives from the Latin word octavus, meaning "eight." It has several usages:

• In music, an octave is the interval equivalent to an eighth.
• In poetry, an octave is most frequently the first eight lines of a sonnet
  • Less commonly, an octave is a distinct poetic form called the Sicilian octave.
• In the Roman Catholic Church, an octave is a feast commemorating the eighth day after a major holiday (which in the late Middle Ages grew to an eight day festival with a specific liturgy) particularly Easter and Pentecost.
• In computing, Octave is a program for performing numerical analysis.
