End rhyme is rhyme that falls on the final words or syllables of lines of verse, as when one line ends with “day” and a later line ends with “away.” The Poetry Foundation glossary calls it the most common type of rhyme, defining it as the rhyming of the final syllables of a line.
End rhymes are what a rhyme scheme maps: the pattern of rhyming line endings in a stanza is labeled with letters, such as ABAB or ABBA. End rhyme differs from internal rhyme, in which a word in the middle of a line rhymes with a word at the end of that line or with another word inside it.
