20. English - Harmonizing the List: The Rules of Parallel Structure

Harmonizing the List: The Rules of Parallel Structure Maintaining parallel structure is vital for creating balanced and readable sentences. When listing items, comparisons, or clauses, writers must use consistent grammatical forms. A frequent mistake is mixing parts of speech, such as combining infinitives with gerunds—for instance, writing "She likes swimming, to read, and biking" instead of "She likes swimming, reading, and biking." Another common error occurs in correlative constructions like either/or or not only/but also, where mismatched phrases disrupt the rhythm. Ensuring uniformity across all paired elements eliminates awkward phrasing and guarantees clarity, precision, and professional quality in your writing.
