In writing prose how can you make sure that readers have a clear understanding of your meaning

Write about each topic one at a time. Be sure to not intermix two separate ideas in order to maintain clarity throughout. Do your best to stay on task and not get distracted or go off on unneeded tangents. I would also suggest to separate each topic/idea into its own paragraph indenting each time. That's my advice on keeping your prose writing clear and concise. Hope this helps!

Ifound this on google “use commas to separate two or more coordinate adjectives that describe the same noun. be sure never to add an extra comma between the final adjective and the noun itself or to use commas with non-coordinate adjectives.” i hope this you for what your looking for
