16. Conclusion

Parallel structure is a powerful tool for clear, balanced, and impressive communication. By keeping all items in a list in the same grammatical form, you can improve your writing and speaking dramatically.

Key points to remember:

• Use same part of speech for all items in a list.
• Keep verbs in the same tense.
• Pair gerunds with gerunds and infinitives with infinitives.
• Repeat prepositions in phrases.
• Use three-item series for emphasis.
• Avoid mixing nouns, verbs, adjectives, and adverbs in a series.

By practicing parallel structure, you will produce writing and speech that are clearer, more professional, and more powerful. This is especially valuable for IELTS, TOEFL, and GRE, where strong grammar and style directly affect your score.

---

Call to Action: Write five sentences using parallel structure. Include at least one three-item series, one gerund pair, one infinitive pair, one adjective series, and one prepositional phrase series. Practice reading them aloud. Then, review an old essay or email and find two examples of faulty parallelism. Rewrite them correctly. Share your work with a teacher or study partner for feedback.
