Matching Parts
Put coordinate ideas in matching grammatical form.
When two or more ideas belong to the same logical tier — items in a list, clauses connected by and or but or or, elements that answer the same question — the grammar of each one should mirror the others. Noun matches noun, verb phrase matches verb phrase, subordinate clause matches subordinate clause. The form is a promise to the reader: these things are equivalent in status. When one element breaks the pattern, the sentence flinches, and the reader's attention snags on the flinch rather than the meaning.
The technique applies anywhere you coordinate: list items in a memo, bullet points in a pitch deck, paired assertions in an argument, series of instructions in a manual. It's especially load-bearing in persuasive writing, where the rhythm of matched parts carries the reader forward and makes a claim feel inevitable rather than assembled.
It does not apply everywhere. Two clauses that aren't actually coordinate shouldn't be forced into parallel just for the sound of it — artificial symmetry is as misleading as a broken one. And matching form can flatten ideas that have genuine hierarchy; sometimes the right move is subordination, not parallelism. The test is logical, not aesthetic: are these ideas truly equal? If they are, match them. If one is the cause and one is the effect, reach for a different tool.
In practice
List with a rogue element
She admires leaders who listen, are decisive, and having empathy.
She admires leaders who listen, decide, and empathize.
All three verbs now match; the list reads as one clean unit instead of three parts fighting each other.
Paired assertions in an argument
The policy saves money, and a reduction in complaints has also been noted.
The policy saves money and reduces complaints.
Trimming to verb + object in both halves makes the claims feel equally solid and lets the reader compare them without friction.
Instruction steps
To apply: rinse the surface, you should let it dry, and the sealant can then be applied in thin coats.
To apply: rinse the surface, let it dry, and apply the sealant in thin coats.
Imperative verb anchors every step; the reader's eye moves through them in identical rhythm.
Common questions
- What is parallel structure in writing?
- Parallel structure means putting grammatically equivalent ideas into matching grammatical form — same part of speech, same tense, same clause type. It keeps lists, paired ideas, and series readable by signaling to the reader that the elements belong to the same logical category.
- How do I fix a parallelism error in my sentence?
- Identify which elements are coordinate — connected by *and*, *but*, *or*, or presented as a list — then pick one grammatical form and apply it to all of them. If the first item is a verb in base form, make every other item a verb in base form.
- Is parallelism always required in a list?
- When list items are genuinely equivalent in logic and status, parallel form is expected and its absence reads as an error. If items are not truly coordinate — say, one is a cause and another is an example — forced parallel can misrepresent the relationship, and restructuring the list is a better fix.
- What's the difference between parallelism and repetition?
- Parallelism is about matching grammatical form, not repeating the same words. *She spoke clearly, persuasively, and with force* has a parallelism problem (two adverbs, then a prepositional phrase) even though no word repeats. *She spoke clearly, persuasively, and forcefully* is parallel without being repetitive.
Inside Verbaria
Verbaria's editor flags coordinate lists and paired clauses where the grammatical forms don't match, highlighting the mismatched element so you can see the break at a glance. The coach can suggest a recast when the fix isn't obvious.
