Grammar Tips for Common Mistakes

1. Unclear pronouns

When there are two or more nouns in a sentence, make sure your reader knows which noun is linked to your pronoun. It鈥檒l get tricky for readers if pronouns are unclear!听听

Unclear: My car hit a plant, but thankfully it wasn鈥檛 damaged.听听

Here, it is unclear whether 鈥渋t鈥 is referring to the plant, or the car.听

Clear: Thankfully, the plant wasn鈥檛 damaged even though I hit it with my car.听

By re-arranging the sentence, readers now understand that 鈥渋t鈥 is referring to the plant.听

2. Misplaced and dangling modifiers

Modifiers give a reader more information about nouns or verbs. They are not grammatically necessary in a sentence, but they can add meaning.听听

Amisplacedmodifier occurs when the modifier is placed far away from what it is modifying. This makes it confusing to know what word the modifier is affecting. To avoid this, place your modifier as close as possible to what it is modifying.听听

Example: Please join us for a discussion of human trafficking at Conestoga College.听听

It is unclear whether Conestoga College is hosting a discussion about human trafficking, or if the discussion is about cases of human trafficking at Conestoga College. Here is a sentence that has been re-arranged to clarify the matter:听

Better:Please join usat Conestoga Collegefor a discussion of human trafficking.听

Adanglingmodifier occurs when a group of words attempts to modify someone or something that鈥檚 not actually stated in the sentence. To avoid this, double check to make sure you鈥檝e included the person or thing the modifier is affecting.听

Example: My parents were expecting their third child at the age of eight.听听听

The sentence above awkwardly implies your parents were expecting a child when they were eight years old. The sentence is missing the subject of the modifier 鈥 who in this case, is the speaker. Here is a sentence that clarifies the matter:

Better:I was eightwhen my parents were expecting their third child.

3. Incorrect subject-verb agreement

It can get confusing for readers when your verb ending does not match or 鈥渁gree鈥 with your sentence鈥檚 subject. Subject-verb agreement mistakes are common when:听

Two singular subjects are joined by and (A and B) to form a plural subject.听

  • Incorrect: The high cost and low revenue of the project was said to be the reason for its cancellation.听
  • Correct: The high cost and low revenue of the project were said to be the reason for its cancellation.听听

There are other nouns between the sentence鈥檚 subject and verb.听

  • Incorrect: The need for standardized tests in education have been challenged the past few years.听
  • Correct: The need for standardized tests in education has been challenged the past few years.听听

The subject is a collective noun (a noun that refers to a group of people or things)听

  • When members of the group are functioning as a single entity, use a singular verb.听
    • Incorrect: The department are on their way here.听
    • Correct: The department is on its way here.听
  • When members of the group are functioning as individuals, use a plural verb.听
    • Incorrect: After work, the group goes their own ways.听
    • Correct: After work, the group go their own ways.听

4. Run-on sentences

A run-on sentence occurs when multiple independent clauses* are put in a single sentence, without any punctuation or connection.听 Run-on sentences are both overwhelming and confusing for readers because they contain multiple independent ideas. Two of the easiest ways to fix run-on sentences are to: (1) separate the clauses into two sentences with a period, or (2) add a comma and a coordinating conjunction**.听

Incorrect:People think social media has more cons than pros I think it really depends on the usage.听

Correct:People think social media has more cons than pros. I think it really depends on the usage.听

Correct:People think social media has more cons than pros, but I think it really depends on the usage.听

* an independent clause is a group of words containing a subject and verb that could stand on its own as a sentence.听听

** coordinating conjunctions are parts of speech that connect words, phrases, clauses, and sentences. For example: 鈥渁nd鈥, 鈥渂ut鈥, and 鈥渙r鈥.

To learn more about run-on sentences, check out the WCC's run-on sentences resource.

5. Incorrect ordering of quotes, punctuation and citations

Sometimes there鈥檚 a lot going on at the end of a sentence and the correct order for quotations, punctuation, and citations can get confusing. While this error doesn鈥檛 have so much to do with clarity in your writing, this is something your academic readers may get critical about!听

An in-text citation falls after the quotation marks and before the period.听

Example: To integrate references, there are 鈥渢hree stages: signaling, situating, and synthesizing鈥 (The University of 蓝莓视频, 2020).听

If there is no in-text citation and you are ending your sentence with a quote, the period falls within the quotation marks.听

Example: My favourite learning resource to recommend people on how to use research in writing is 鈥淚ntegrating Evidence Effectively.鈥澨
