What do you call it when two or more consonants with different vowels are repeated?

Answer 1

Alliteration is the act of repeating a consonant sound, either within a word (cacophony) or in two or more consecutive words (Bob's Big Boy).

If a vowel sound is repeated instead, it's called assonance (e.g., Adam's apple).

Answer 2

This is known as consonance, where consonants are repeated with different vowels following them. This literary device is often used in poetry and prose to create rhythm and sound patterns.
