"stream..."See in text(The Song of Wandering Aengus)
Yeats was such a master of slant rhyme that the technique is often referred to as “Yeatsian rhyme.” A Yeatsian rhyme is defined by a loose, subtle connection between end-rhyming words. Often in such a rhyme, the consonants are different but there exists a connecting vowel sound; or, conversely, the vowel sounds will be different but a hint of a consonant sound will connect the words. “Wing” and “stream” are faintly connected by their final consonant sounds. In the first stanza, “wood” and “wand” form a rim rhyme: the words begin and end with w and d sounds.
