Do couplets have to rhyme?

As a language expert with a deep appreciation for poetry, I can tell you that couplets are a form of verse that consists of two lines that are usually related in some way. They can be related thematically, metrically, or, as is often the case, through the use of rhyme. Rhyme is a powerful tool in poetry that can create a sense of unity and closure, and it's a feature that many poets have used to great effect throughout history. However, it's important to understand that while rhyme is a common and traditional feature of couplets, it is not a strict requirement for all couplets.

In English poetry, a heroic couplet is a type of couplet where both lines are written in iambic pentameter. This means that each line has five 'iambic' feet, which are metrical units consisting of an unstressed syllable followed by a stressed syllable (da-DUM). The term 'heroic' comes from the elevated and often serious tone of the content, which was traditionally used to discuss grand or noble themes. Not all heroic couplets rhyme, but many do, and when they do, it often enhances the formality and balance of the verse.

The use of white space in poetry can serve many purposes. It can indicate a pause, a shift in thought, or a break in the narrative. When it comes to couplets, white space can also be used to visually separate the two lines, whether they rhyme or not. This can help to highlight the relationship between the lines, even if that relationship isn't based on sound.

Poetic epigrams are another form that often employs the couplet structure. An epigram is a short, witty saying or poem that often conveys a pointed observation or a clever insight. Epigrammatic couplets can be found in a variety of poetic forms, and not all of them rhyme. The focus in an epigram is often on the cleverness of the language and the impact of the message, rather than on the sound of the words.

In conclusion, while rhyme is a traditional and frequently used feature in couplets, it is not a hard and fast rule. Poets have the freedom to experiment with form and structure, and many have chosen to write couplets that do not rhyme. The beauty of poetry lies in its flexibility and the endless possibilities it offers for expression and communication.

While couplets traditionally rhyme, not all do. Poems may use white space to mark out couplets if they do not rhyme. Couplets in iambic pentameter are called heroic couplets. ... The Poetic epigram is also in the couplet form.
