Rhyme
German

Because German phonology features a wide array of vowel sounds, certain imperfect rhymes are widely admitted in German poetry. These include rhyming "e" with "ä" and "ö", rhyming "i" with "ü", rhyming "ei" with "eu" (spelled "äu" in some words) and rhyming a long vowel with its short counterpart.

Some examples of imperfect rhymes (all from Friedrich Schiller 's " An die Freude "):
