What purpose do paragraphs serve as we communicate? How do you approach them in your writing?

Paragraphs help the readers understand the reasoning behind an idea developed in a text. To make reading easier, paragraphs shouldn´t be too long and all of them should have a particular purpose, whether it is to make a claim, provide evidence, establish a transition from a subject to another, or anything else.

Explanation:

I try to make a draft before writing to make sure that I have all the information I need and then I establish a structure that enables me to explain it in an organized sequence. Paragraphs allow me to separate the information depending on whether I want it to be part of the introduction, the development, or the conclusion, and then I build paragraphs to organize the information.  

i guess you are missing the idea that has to be supported, am i right?

they are direct opposites. they can both be corrupted. they are inseparable.
