What term describes the repetition of similar vowel sounds in stressed syllables?

The term that describes the repetition of similar vowel sounds in stressed syllables is assonance. This literary device is used to create rhythm, enhance mood, or reinforce meaning within a line of poetry or prose. By repeating vowel sounds, assonance can help to unify a piece of writing, making it more melodic and engaging for the reader.

In contrast, consonance refers to the repetition of consonant sounds, usually occurring at the end or in the middle of words, which serves a different purpose in creating sound patterns. Diction pertains to word choice and the clarity and style of expression in writing, while stream of consciousness is a narrative technique that attempts to capture the flow of thoughts and feelings in a character's mind. Understanding these distinctions around assonance enhances comprehension of sound devices in literary works.
