Clarity is often subtraction.

Most attempts at clarity involve adding, another explanation, another example, another qualifier, when the confusion is usually being caused by what is already there. Removing the extra clause, the unnecessary option, the redundant sentence, tends to do more than any addition. What is left becomes visible once the surrounding material is gone.

When something is unclear, try deleting before explaining. Cut the least essential third and read it again. The remaining version is usually closer to what you meant.
