Rhyme is the similarity in sound of the ends of words: the last stressed syllable and the following unstressed syllables (if any). Rhyme is usually a structuring device in verse. Of course not all poetry rhymes: classical Greek and Latin poetry never rhyme, for instance. When rhyming verses are arranged into stanzas, we can identify the rhyme scheme by assigning letters each rhyme, beginning with a and proceeding through the alphabet. Couplets, for instance — such as Pope's

'Tis hard to say, if greater want of skill
Appear in writing, or in judging ill;
But of the two, much greater is th' offence
To tire the patience, than mislead the sense
— rhyme aa bb, and so on -- a represents the ill sound, b represents the ence sound. A quatrain such as
Far from the madding crowd's ignoble strife,
Their sober wishes never learned to stray;
Along the cool sequestered vale of life
They kept the noiseless tenor of their way
is said to rhyme abab, where a represents ife, and b represents ay. More complicated patterns can be described the same way: the sonnet, for instance, can be abab cdcd efef gg or abba abba cdecde; the Spenserian stanza rhymes ababbcbcc.

Most rhymes appear at the end of lines, but internal rhyme is the appearance of similar sounds somewhere in the middle of a verse. Words in the middle can rhyme with other words in the middle or words at the end of lines.
