A haiku by Masaoka Shiki
Nure-ashi de suzume no ariku rôka kana:
Hops along the verandah,
with wet feet.
HAIKU was given its name by the writer Masaoka Shiki in the 19th century. Haikus consists of 17 moras, in three units: 5, 7 and 5 in each. There are also some rules applied to it: there has to be a kigo, a symbolical seasonal reference, many times difficult to understand as they are often metonyms and a surprising turn, usually introduced by a kireji, a cutting word (e.g. ya or wa).
