Which term describes the repetition of initial consonant sounds in neighboring words?

The correct term for the repetition of initial consonant sounds in neighboring words is alliteration. This literary device is commonly used in poetry and prose to create rhythm, enhance mood, and make phrases more memorable. For instance, in a phrase like "wild and wicked," the "w" sound is repeated at the beginning of each word, demonstrating alliteration.

The other terms do not pertain to this specific concept of sound repetition. A metaphor refers to a figure of speech that implies a comparison between two unlike things, personification attributes human qualities to non-human entities or abstract concepts, and a simile makes comparisons using "like" or "as." These literary devices serve different purposes in writing and do not focus on the repetition of consonant sounds.
