Alliteration is the repetition of the same sound or letter at the beginning of each or most of the words in a sentence. The easiest way to use alliteration would be to repeat the starting letter of the words.
Alliteration:
A literary technique known as alliteration involves using a series of words with the same consonant sound at the beginning of each one. The words may be placed next to one another directly or only near enough to one another to be seen. It is typically employed in poetry as a sound-producing instrument.
How to use alliteration?
You should probably tone it down if, when you read it again, it comes out as campy or sing-songy (even if that wasn't your intention). There is such a thing as having too much of something. It could be a bit much if you tip over more than four alliterated words in a row. Repeating the same consonant across an entire work in alliterated phrases could be entertaining.
Similar to a rhyme system, focusing on alliteration before composing a work will limit your word choices and originality.
Draft your essay completely, then edit in some alliteration where it would naturally belong.
Usually, editing a piece of writing to make it what you want it to be is simpler than trying to write it that way from the start.
Try out alliteration as you like if you've never done it before. Throw off all the guidelines I've provided so far and experiment with a variety of styles.
Alliteration may be used more purposefully with practise, but experimenting is one of the finest aspects of writing.
