A Haiku is VERY simple.
The haiku is a Japanese poetic form that consists of three lines, with five syllables in the first line, seven in the second, and five in the third.
What is a syllable?
A syllable is a part of a word that contains a single vowel sound and that is pronounced as a unit. So, for example, ‘book’ has one syllable, and ‘reading’ has two syllables.
