What is identified by identical or similar final sounds in words, especially at the end of lines in poetry?

The concept of identical or similar final sounds in words, particularly at the end of lines in poetry, is referred to as rhyme. This technique involves the repetition of sounds that typically occurs in two or more words, enhancing the musical quality of the verse. Rhyme can add rhythm and can also create a sense of closure or connection between lines, contributing to the overall aesthetic of the poem.

In poetry, rhyme schemes can vary and can include end rhyme, where the rhyming words come at the ends of lines, and internal rhyme, where the rhyme occurs within a single line. The use of rhyme helps to engage readers and can make the text more memorable.
