Dhugal Lindsay (Yokosuka, Japan) believes English language haiku should aspire to be:

"Short poem of rhythmical structure, usually between 7 and 17 syllables in length. It contains a reference to a seasonal or otherwise natural entity, is concrete, and illuminates some aspect of the existence of one or more of the elements or entities within the poem."

Dhugal and John Bird collaborated for this short description:

"A haiku is a brief poem, built on sensory images from the environment. It evokes an insight into Our world and The world."

Cynthia Ludlow (Brisbane, Qld)

"Haiku are small nature poems that I don’t understand but know to be true."
