2. What is Parallelism
Definition
Why Use it
Parallel structure (also called parallelism) is the repetition of a chosen grammatical form within a sentence. By making each compared item or idea in your sentence follow the same grammatical pattern, you create a parallel construction

All items in a series should have the same structure to help the reader quickly process information. If one element is an adjective, then all elements should be adjectives; if one element is a noun, then all elements should be nouns; if one element is a verb, then all elements should be verbs, and so forth. Take a look at the examples below: 1. The children are energetic and noisy. = adjective + adjective 2. She bought a skirt and a blouse. = noun + noun 3. He walked slowly and confidently to the witness stand. = adverb + adverb When items in a series do not have the same form, the sentence will sound awkward and out of balance.

6. Revising to create parallel structure...
An easy way to check for parallel structure in a piece of writing, whether that structure is between words, phrases, clauses, or paragraphs in an essay, is to think of the core idea in the structure as the trunk of a tree, and each parallel item as a branch off that trunk; once you find the trunk, follow the trunk line to each of the branches directly, checking to ensure that the trunk connects strongly (and correctly) to each branch as illustrated in the diagram below:
