Free verse and rhyming poetry are often said to be in opposition. But, really, they are just different versions of what poetry does. Just as a rhyming poem is built up out of a pattern of repeating end sounds, in some pattern or even irregularly, a poem can rhyme conceptually: that is, through ideas that relate in some way, obvious or hidden. Through their redness, “rose” and “fire truck” rhyme conceptually, as do “deconstruction” and “deep sea diving” (Jacques Derrida and Jacques Cousteau). It can not only be fun to conceptually rhyme, but also be good practice to write formal poems that use conceptual, as opposed to sonic, rhymes. A poem that seems too static because it is locked into a single idea, or a rigid expository framework, can often become both looser and also more true when the poet allows ideas to rhyme conceptually. Conceptual rhyme is not merely a pleasure for poets, but very close to the purpose of poetry, to provide a place for associative thinking.
