What is an end rhyme?
There are two kinds of "end rhymes." The first, is a rhyme in which the last word at the end of each verse is the word that rhymes.
The second type of "end rhyme" generally refers to words that rhyme on their "end" or last sound, which consists of the final vowel sound and all following sounds. This isn't necessarily the last syllable. For instance, if you rhymed "bungee" with "me," the "-ee" in "bungee" is what is meant by an "end" rhyme.
An end rhyme is a rhyme where the sound consisting of the final vowel sound and all following consonants is exactly the same as another word. It doesn't necessarily mean that the final syllables are the same, because in a syllable you could have a consonant sound preceding a vowel sound. If the sounds of the final syllables of two words are the same, then that would be called a "last syllable rhyme." Here's an example: "Constable" has the last syllable "-ble." That means that any word with that same exact sound would be a last syllable rhyme. Therefore, "tenable" and "edible" are last syllable rhymes of "constable." However, an end rhyme of the word "constable" does not necessarily include the "b" sound found in the last syllable. Instead, any word ending with the sound "uhl" would be an end rhyme. Therefore, "angel" and "barrel" are both considered end rhymes of "constable."
Some background is in order. Part of what is considered to make two words rhyme is that they not only sound alike, but that the portion of the word that sounds alike is the "tonic" or accented syllable of the two words. The tonic syllable in "bungee" is "bun-" so under "normal" circumstance, it would not be considered to rhyme with words like "me" or "agree."
Generally it is a rhyme of the last word (or the last syllable) of two or more lines of verse. For poetic rhymes, they may be considered words that rhyme only in the syllable that is at the end of the words. Examples: Eaten, rotten.
