10 Common Grammar and Punctuation Errors That Plague Even the Best Editors

Proofreader Grammar Toolkit

We've all been there: eyes glued to a manuscript, red pen poised, ready to vanquish the demons of grammar and punctuation. But even the most seasoned proofreader can encounter those pesky errors that seem to sneak past every filter. Fear not, fellow wordsmiths! Today, we're armed with a toolkit to tackle ten of the most common grammatical and punctuation errors in the English language.


A Proofreader's Grammar Toolkit

1. Subject-Verb Agreement: This classic involves ensuring the verb in a sentence "agrees" with the number (singular or plural) of its subject. Common mistakes include:

  • "The data is..." (should be "are")

  • "Everyone enjoys their..." (should be "enjoys his/her")

Tip: Identify the subject, then ask if it's singular or plural. Choose the verb that matches!


2. Comma Splices and Run-on Sentences: These punctuation terrors occur when commas are misused to join independent clauses, creating a Frankenstein's monster of a sentence.

  • "I love dogs, they're so cuddly." (comma splice)

  • "I woke up, ate breakfast, brushed my teeth, and went to work." (run-on)

Solution: Use semicolons, conjunctions, or periods to separate independent clauses.


3. Misplaced Modifiers: These sneaky critters dangle at the beginning of a sentence, modifying the wrong element.

  • "Walking down the street, a bird chirped." (Who was walking?)

Revise: Place the modifier closer to the element it modifies, or rewrite the sentence for clarity.


4. Apostrophe Abuse: This punctuation mark is often used (or misused) for possessives and contractions. Remember:

  • Possessives: Singular nouns get "'s," plurals get "s'." (e.g., dog's, cats')

  • Contractions: They combine two words with an apostrophe replacing omitted letters. (e.g., can't = cannot)

Beware: Don't use apostrophes for plurals!


5. Confusing Homophones: These words sound alike but have different meanings and spellings. Watch out for:

  • Their/there/they're

  • Who's/whose

  • You're/your

Context is key! Choose the word that makes grammatical sense in the sentence.


6. Dangling Participles: These verb forms modify nouns not directly connected to them, creating confusion.

  • "Smiling, the cake was devoured." (Who was smiling?)

Fix: Reconnect the participle to its noun or rewrite the sentence.


7. Misused Semicolons: These mighty punctuation marks separate independent clauses more closely related than with a period. Don't use them:

  • Between items in a list.

  • To join a dependent clause to an independent clause.

Use commas or periods in these cases.


8. Oxford Comma: This comma before the final "and" in a list is optional in American English. However, for clarity and consistency, many style guides recommend using it.


9. Clichés and Overused Phrases: These tired expressions can weaken your writing. Seek fresher alternatives to phrases like "at the end of the day" or "think outside the box."


10. Inconsistent Verb Tense: Ensure verbs throughout your writing agree in tense (past, present, future) unless there's a deliberate shift in time.


Remember, proofreading is an art, not a science. These are just some common errors to watch for. By honing your skills and using this toolkit, you'll be slaying grammatical dragons and polishing prose to perfection in no time!


Bonus Tip: Read your work aloud! This often helps catch awkward phrasing and grammatical errors that might slip past your eyes.
