The yadu (Burmese: ရတု, Burmese pronunciation: [jadṵ]; also spelt ya-du and yatu) is a Burmese form of poetry which consists of up to three stanzas of five lines. The first four lines of a stanza have four syllables each, but the fifth line can have 5, 7, 9, or 11 syllables. A yadu should contain a reference to a season.
The form uses climbing rhyme. The rhyme is required on the fourth, third, and second syllables of both the first three lines and the last three lines.
