Half rhyme, also known as slant rhyme or near rhyme, occurs when two words have similar but not identical sounds. This technique often involves matching consonants while the vowel sounds differ, creating a subtle connection between the words. For example, "shape" and "keep" exemplify half rhyme, as they share the ending consonant sound but differ in their vowel sounds. Writers use half rhyme to add a unique rhythm and texture to their poetry or lyrics. It allows for greater flexibility in word choice while still maintaining a sense of cohesion. This technique is commonly found in the works of poets like Emily Dickinson and Walt Whitman, enhancing the emotional depth of their writing.
