Grammar Rule in 30 Seconds
Parallel structure means using the same grammatical form for all items in a list to ensure clarity and professional rhythm.
- Match parts of speech: If the first item is a noun, make them all nouns. Example: 'Apples, pears, and grapes.'
- Match verb forms: Don't mix gerunds and infinitives. Example: 'I like hiking, swimming, and running.'
- Match clause types: Keep the same voice (active/passive) throughout. Example: 'He opened the door, entered the room, and sat down.'
مرور کلی
and، or و but به هم متصل میشوند، باید از یک نوع دستوری (Grammatical Category) پیروی کنند. اگر اولین آیتم یک اسم باشد، تمام آیتمهای بعدی باید اسم باشند. اگر اولین آیتم یک فعل به صورت مصدر (Infinitive) باشد، بقیه نیز باید مصدر باشند.She enjoys reading, writing, and to learn را در نظر بگیرید. ناهماهنگی to learn بلافاصله مشخص است. اصلاح آن به She enjoys reading, writing, and learning تعادل را باز میگرداند.reading، writing و learning همگی اسم مصدر (Gerund) هستند که نقش اسمی ایفا میکنند. در فارسی، ما معادلهایی برای اینها داریم (مثلاً «خواندن»، «نوشتن» و «یاد گرفتن»)، اما چون در فارسی اینها اسم هستند، ناهماهنگی دستوری به آن شدتی که در انگلیسی حس میشود، آزاردهنده نیست. هدف شما باید ایجاد یک الگوی مشخص در ابتدای لیست و رعایت دقیق آن تا انتها باشد.A, B, and C است که در آن A، B و C از نظر دستوری معادل هستند. این معادل بودن فراتر از تطابق ساده اجزای کلام است؛ بلکه نیاز به تطابق «فرم» (Form) دارد. برای مثال، اگر از مصدر بدون to استفاده میکنید، تمام افعال باید بدون to باشند.and در لیستهای سه تایی یا بیشتر، برای شفافیت بسیار مهم است. در فارسی، ما معمولاً از «و» استفاده میکنیم و ویرگول قبل از آن در لیستها مرسوم نیست، اما در انگلیسی آکادمیک، این ویرگول از ابهام جلوگیری میکند.Noun, Noun, and Noun | She values honesty, integrity, and diligence. | همه موارد اسمهای انتزاعی هستند. |Adj, Adj, and Adj | The exhibition was insightful, thought-provoking, and inspiring. | همه موارد صفتهای توصیفی هستند. |Base, Base, and Base | You must plan, execute, and evaluate your strategy. | همه افعال پایه هستند (بعد از must). |Gerund, Gerund, and Gerund | His hobbies include running, cycling, and painting. | همه موارد فعل ingدار هستند. |to+V, to+V, and to+V | Their goal is to explore, to discover, and to innovate. | همه موارد مصدر با to هستند. |- در نوشتن رسمی: برای بیان اهداف پژوهش، استفاده از ساختار موازی حیاتی است. مثلاً:
The study aimed to identify factors, to analyze relationships, and to propose solutions.این جمله بسیار حرفهایتر از جملاتی است که در آنها فرم افعال تغییر میکند. - در ارتباطات حرفهای: وقتی در یک ایمیل اهداف خود را لیست میکنید، رعایت این ساختار باعث میشود خواننده سریعتر نکات کلیدی را درک کند.
- در سخنرانی: استفاده از ساختار موازی ریتمی ایجاد میکند که به مخاطب کمک میکند پیام شما را به خاطر بسپارد. این همان تکنیکی است که سخنرانان بزرگ جهان برای تأکید بر نکات کلیدی استفاده میکنند.
- 1ترکیب اجزای کلام (Mixing Parts of Speech): این رایجترین اشتباه است. زبانآموزان اغلب به معنای کلمات توجه میکنند نه نقش دستوری آنها. مثلاً:
I enjoy hiking, painting, and beautiful scenery.در اینجاhikingوpaintingاسم مصدر هستند، اماbeautiful sceneryیک گروه اسمی است. دلیل این اشتباه این است که در فارسی ما به راحتی میتوانیم اینها را کنار هم بگذاریم بدون اینکه ساختار جمله به هم بریزد. اما در انگلیسی، این تداخل باعث ناهمگونی میشود.
- 1عدم تطابق فرم فعل: مثلاً
She decided to study, travel, and had found a job.در اینجاto studyوtravel(مصدر) باhad found(ماضی بعید) ترکیب شدهاند. این اشتباه به دلیل این رخ میدهد که زبانآموز به ترتیب زمانی وقایع فکر میکند (اول درس خواند، بعد سفر کرد، بعد شغل پیدا کرد) و نه به ساختار موازی. در فارسی، چون فعل در انتهای جمله است، ما کمتر با این مشکل مواجه میشویم و این تداخل افعال در انگلیسی برای ما ناخودآگاه رخ میدهد.
- 1سردرگمی در صفت و قید: مثلاً
The team was innovative, collaborative, and worked efficiently.در اینجا دو صفت داریم و یک عبارت فعلی با قید. این برای یک انگلیسیزبان کاملاً ناموزون است. باید بنویسید:The team was innovative, collaborative, and efficient.این اشتباه ناشی از انتقال مستقیم ساختار فارسی است که در آن قید و صفت به راحتی در کنار هم در یک لیست قرار میگیرند.
He likes to swim, playing, and run. | He likes to swim, to play, and to run. |The movie was long, boring, and it cost a lot. | The movie was long, boring, and expensive. |She is smart, talented, and has a lot of energy. | She is smart, talented, and energetic. |- 1آیا همیشه باید از ویرگول آکسفورد استفاده کنم؟

Meanings
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 cohesive and balanced flow.
Word-Level Parallelism
Matching individual words like nouns, adjectives, or adverbs in a simple list.
“The workshop was informative, engaging, and practical.”
“We need to act quickly, decisively, and effectively.”
Phrase-Level Parallelism
Matching phrases such as gerund phrases (-ing), infinitive phrases (to...), or prepositional phrases.
“He enjoys reading historical novels, watching indie films, and playing classical guitar.”
“To succeed is to work hard, to stay focused, and to remain humble.”
Clause-Level Parallelism
Matching entire clauses, ensuring they all use the same voice (active/passive) or tense structure.
“The coach told the players that they should get plenty of sleep, that they should eat a healthy meal, and that they should arrive early.”
“What we say is what we do, and what we do is who we are.”

Smart Tips
Check the ending of each word. If the first two end in -ly, the third one probably should too.
Start every bullet point with a past-tense action verb.
Place the 'not only' immediately before the word you are comparing.
Repeat the 'anchor' word (like 'that' or 'to') to help the reader stay on track.
تلفظ
List Intonation
When speaking a parallel list, use a rising intonation for each item except the last one, which should have a falling intonation.

سوالات متداول (8)
No, you can say 'to eat, to sleep, and to dream' OR 'to eat, sleep, and dream.' Just don't mix them like 'to eat, sleep, and to dream.'
Technically yes, because gerunds function as nouns (e.g., 'I like pizza and swimming'). However, for stylistic C1 writing, it is often better to keep them identical.
Yes! If your first bullet point starts with a verb, all of them should start with a verb in the same tense.
It is when you attempt to create a list but use different grammatical forms, like 'He is smart and a hard worker.'
Absolutely. Whatever follows 'either' must match whatever follows 'or.' For example: 'either at home or at work.'
It helps the listener follow your logic. If your structure is messy, the listener has to work harder to understand you.
Usually no. If you are listing actions in the past, keep them all in the past: 'He came, he saw, he conquered.'
Yes, the rules of parallelism are universal across all standard dialects of English.
