Parallelism involves using consistent and repeating grammatical structures to indicate equal importance. It is commonly used with words, phrases, clauses, and lists joined by coordinating conjunctions like "and" or "or." Maintaining parallel structure provides clarity and emphasizes relationships between ideas. Deviating from parallel structure can confuse or mislead readers.

2. Definition: Parallelism
 Parallel structures use a repeating
pattern of words to indicate that the
words, phrases, or clauses are of the
same level of importance.
 The most common way to join parallel
structures is with a coordinating
conjunction like “and” or “or.”

throughout the structure.
