Final answer:
Rhyme in poetry is the repetition of similar or identical sounds, commonly observed as end rhyme in formal verse. It adds a musical quality, making poetry memorable and pleasant to experience. Rhyming can also occur within lines, known as internal rhyme.
Step-by-step explanation:
Rhyme is a poetic device involving the repetition of similar or identical sounds at the end of, or within, different lines of verse. In formal verse, rhyme often takes the form of end rhyme, where words at the ends of two or more lines sound alike. An example of this would be using the words 'time' and 'rhyme' at the ends of two successive lines in a poem. It is distinct from consonance, which is the repetition of consonant sounds, and from eye rhyme, where words look similar but do not sound alike. Rhyme serves to add a musical quality to poetry, making it more memorable and enjoyable to read or listen to.
In the realm of poetry, language becomes not just a tool for communication but a means to create aesthetic pleasure and evoke emotion. Through devices like rhyme, poets enhance the rhythmic qualities of language, which can make their work more evocative or impactful. Rhyming can occur as internal rhyme within lines or as end rhyme at the end of lines, depending on the structure and style of the poem.
