Types of rhymes

Perfect rhyme

The final stressed vowel and everything after it match: light / night, mountain / fountain.

It is the most closed and the most audible kind. It gives a sense of completion and symmetry — and for that very reason it can sound predictable across a whole text without variation.

Rich rhyme

The consonant before the stressed vowel matches too: light / delight, rain / refrain.

The Princeton Encyclopedia of Poetry and Poetics keeps this as a category of its own, and it is worth knowing because English poets use it far less than French ones do. It closes a line harder than a perfect rhyme, which makes it emphatic — and easy to overuse.

Slant rhyme

Also called half rhyme, near rhyme or pararhyme: the sounds resemble each other without matching. A shared vowel with different consonants (home / bone), or shared consonants with a different vowel (bad / bed).

It is quieter and far more flexible. It sustains the music without closing the line, which makes it useful across long texts where continuous perfect rhyme would turn insistent. Emily Dickinson built most of her work on it, decades before the term existed, and Wilfred Owen used consonant pararhyme deliberately to keep his war poems from resolving.

Internal rhyme

Rhyme does not have to sit at the end of the line. Two words rhyming inside one line, or across the middle of two consecutive lines, create a faster and less solemn echo.

It is common in song, where the ear has less time than in reading, and it is the backbone of most rap: the rhyme density is high enough that end-rhyme alone would not carry it.

Eye rhyme

Two words that look as if they rhyme and do not: love / move, cough / bough. English spelling produces these in quantity.

Some are historical — they rhymed when they were written and stopped as pronunciation shifted, which is why several of Shakespeare's sonnets appear to fail on their final couplet. Others are deliberate. Either way, an eye rhyme works on the page and disappears when the poem is read aloud, so it is worth knowing which you are relying on.

Schemes

How rhymes are arranged in a stanza — couplet, alternating, enclosed — changes how the reader groups the lines. An alternating rhyme holds tension from one line to the next; a couplet resolves it immediately.

Choosing a scheme is deciding where the reader will rest. The English sonnet makes this structural: twelve lines of alternating rhyme hold the argument open, and the closing couplet — the only two lines that rhyme with each other — is where it shuts.

The most exact rhyme is not always the one that best serves the text.

Choosing between candidates

A rhyme list is a starting point. The choice depends on meaning, register, and what the word does to the line.

The rhyming dictionary in Ilena sits beside definitions and synonyms for exactly that reason: you often need to know what a candidate means before you can judge it.
