Alliteration is a stylistic device where words in a series begin with the same consonant sound. It can add humor and expression to writing, though it may not deepen meaning. Alliteration makes words more engaging and entertaining, helping audiences pay attention and remember. While not essential to depth, alliteration livens up language with creative phrasing. It is commonly found in sayings, poetry and brand slogans where memorability is key. Spotting and crafting alliterative phrases develops understanding and expressive use of the technique.
