Final answer:
In Haiku, a traditional Japanese poetic form, the term 'kireji' refers to a cutting word that offers a moment of pause or contrast within the poem, adding depth and juxtaposition.
Step-by-step explanation:
Haiku is a well-known Japanese form of poetry that is composed of three lines featuring a syllable pattern of 5-7-5. One important element of traditional Haiku is the kireji, which is a cutting word that provides a pause or a break in the rhythm, often introducing an emotional or reflective moment. These cutting words are used to convey subtle nuances and to divide the poem into two parts, providing a juxtaposed effect that is characteristic of Japanese aesthetics.
