Final answer:
Alliteration is a form of figurative language that involves the repetition of initial consonant sounds, creating a musical and memorable effect in writing.
Step-by-step explanation:
Alliteration is indeed a form of figurative language and the statement is true. It involves the repetition of initial consonant sounds in multiple words close to each other, such as 'silly snakes slither silently'. Alliteration can create a musical effect in poetry and prose, enhancing the aesthetic quality of the text and making it more memorable. For example, in the poem "There Come Soft Rains" by Sarah Teasdale, you can see alliteration which adds to the sound in poetry.
Other types of figurative language include simile, in which one thing is compared to another using 'like' or 'as'; metaphor, which makes a direct comparison without using 'like' or 'as'; and assonance, which is the repetition of vowel sounds within words. Each of these tools helps poets and writers to evoke sensory experiences, add layers of meaning, and express complex concepts in a vivid manner.
