A bayt (Arabic: بَيْت, romanized: bayt, pronounced [bajt], lit. 'a house') is a metrical unit of Arabic, Azerbaijani, Ottoman, Persian, Punjabi, Sindhi and Urdu poetry.
In Arabic poetry, a bayt corresponds to a single line divided into two hemistichs of equal length, each containing two, three or four feet, or from 16 to 32 syllables. In Persian, Turkic and Urdu poetry, the word bayt has come to refer to two lines (like a couplet, although the two lines of a Persian, Turkic or Urdu bayt do not have to rhyme).
