Parallel structure or parallelism is used when words are united by grammatical forms. The lack of a parallel structure can disrupt the rhythm of the sentence, where the sentence is grammatically unbalanced.

By associating related ideas, the point of analysis is emphasized, the arguments are connected, easily visible and in this way the analysis is clear and easy to understand.
