Here's a breakdown:
* Repetition of Vowel Sounds: The key is the repetition of the vowel sound, not necessarily the exact spelling of the vowel.
* Proximity: The words with the repeated vowel sounds must be close enough to each other to be noticeable, typically within the same line or phrase.
* Effect: Assonance can create a range of effects, including:
* Emphasis: Highlighting particular words or phrases.
* Rhythm: Creating a sense of flow and musicality.
* Mood: Evoking specific emotions or atmospheres.
Example:
* "The cat sat on the mat." - This simple sentence has assonance with the repetition of the short "a" sound in "sat," "on," and "mat."
Other Examples:
* "The rain in Spain falls mainly on the plain." (Repetition of the "ai" sound)
* "The lonely crow flew high above the low-lying fog." (Repetition of the "o" sound)
* "Hear the mellow wedding bells." (Repetition of the "e" sound)
Remember: Assonance differs from consonance, which involves the repetition of consonant sounds.
