With regard to rhyme, end rhyme, internal rhyme and holorhyme all deal with the rhyming of the last word of one line with the last word of another line. The sound of the words must be the same to create a rhyme: "boat" and "bore" don't rhyme, but "boat" and "tote" do rhyme, even though the spelling is different. Most often the rhyme depends on the sound of the vowel repeated. Again, "boat" and "tote" (in perfect rhyme) have the same long "o" sound.
With this said, end rhyme (known also as "tail rhyme" or "rime couée") exists when two words at the end of two separate lines rhyme. They may be next to each other as presented in rhyming couplets. Note the couplet from Shakespeare's Sonnet 29:
For thy sweet love rememb'red such wealth brings
That then I scorn to change my state with Kings.
Note that "brings" found at the end of the thirteenth line of this sonnet rhymes with "Kings," the last word of the fourteenth line.
Another form of rhyme that involves the word at the end of a line in poetry can be found in poems by many writers, but see this example from Edgar Allan Poe (not often thought of as a poet), in his famous poem, "Annabel Lee:"
For the moon never beams without bringing me dreams...
In this line, the last word is "dreams," which rhymes with the word "beams," found in the middle of the line. (This is called "internal rhyme".)
Holoryhme (also called "holorime") occurs when the entire line rhymes with another line—entirely. This is a much more unusual rhyming pattern; however, the last words in the two lines rhyme—as do all the other words in the lines. See the following:
In Ayrshire hill areas, a cruise, eh, lass?
Inertia, hilarious, accrues, hélas!
...from Miles Kington's poem titled "A Lowlands Holiday Ends in Enjoyable Inactivity"...
All of these examples involve the rhyme created with the last word of a line, in two or more lines, that share the same sound.
