What is the difference between alliteration and rhyme?

Alliteration and rhyme both involve repeating parts of a word. However, they repeat different parts of a word.

Whereas alliteration involves repeating the initial sound of a word (e.g., “slithering snake”), rhyme involves the repetition of ending sounds (e.g., “blue” and “flu”). Because of this, alliteration is also known as initial rhyme or head rhyme (to distinguish it from end rhyme).
