-

-

-
Breath vs. BreatheBreath is the air taken into or expelled from the lungs. Example: It was a breath of fresh air to meet someone so genuine. Breathe is to take air into the lungs and then expel it, as a regular physiological process. Example: After being cooped up for so long, it felt wonderful to breathe fresh air.
-
Bring vs. TakeWhen using these words as commands think in terms of direction. People bring things toward you and take things away from you. Example 1: Please bring your report to my office. Example 2: Please take this report to the receptionist.
-
Continual vs. ContinuousContinual means something that's always occurring, with obvious lapses in time. Example: The continual music next door made it the worst night of studying ever. Continuous means something continues without any stops or gaps in between. Example: Her continuous talking prevented him from concentrating
-
Different From vs. Different ThanDifferent from is comparative and typically requires a noun or noun form to complete the expression. Example: My birthday this year was different from what it was last year. Different than is used to draw distinction and may be followed by a clause. Example: My birthday this year was different than it was last year. * When in doubt, use “different from.”
-
Farther vs. FurtherThe word farther implies a measurable distance. Example: I threw the ball ten feet farther than Bill. Further should be reserved for abstract lengths you can't always measure. Example: The financial crisis caused further implications.
-
Fewer vs. LessFew and fewer are for things you can quantify. Example: The firm has fewer than ten employees. Less is used for hypothetical quantities. Example: The firm is less successful now that we have only ten employees.
-
Irregardless and UnthawThese are not words. Regardless and Thaw are sufficient and don't need any senseless prefixes mucking them up.
-
Its vs. It'sIts is a possessive form of the pronoun it, meaning belonging to it. Example: The car needed its brakes repaired. It's is a contraction of the words it is or it has. (Interestingly, we don’t really contract it was into it’s.) Example: It’s been so long since we saw you!
-
Lose vs. LooseLose is what happened to you when you can't find your keys, you have to settle a bet, or were beat in a game. Example: Did you lose the car keys?

-
May vs. MightMay implies a possibility. Example: "I may go to the store" means I probably will go to the store. Might implies far more uncertainty. Example: "I might go to the store" means it's unlikely that I'll go to the store.
-
Me vs. Myself vs. IChris and me? Chris and I? Chris and myself? The easiest way to avoid using the wrong one is to remove everyone else from the statement, and then see if it still makes sense. I is the subject pronoun, which means it performs the action of the verb. Example: I sent the email to Chris. Me is the object pronoun. That means it is acted upon. (In the example above, “Chris” is the object). Example: Chris sent the email to me. Myself is the reflexive object pronoun. The difference here is that reflexive objects are actions you perform on yourself. Example: I sent the email to myself.
-
NorNor expresses a negative condition, literally meaning "and not." You are obligated to use nor if your sentence expresses a negative and follows with another negative condition. Example: Neither the men nor the women were drunk.
-
Principle vs. PrincipalA Principle is a rule, a law, a guideline, or a fact that helps you know what is right and wrong and that influences your actions. Example: There exist certain fundamental principles of human rights. A Principal is the headmaster of a school or a person who's in charge of a company. Principal can also be used as an adjective to mean original, first, or most important. Example: She is the principal cellist of the orchestra. * A trick for keeping the two straight: The "a" in principal is first in the alphabet, just like a principal is someone who's first in rank.
-
Since vs. BecauseSince refers to time. Example: Since I graduated from college, I’ve married and had two children. Because refers to causation. Example: Because I started running more frequently, I wear through my shoes more quickly.
-
That vs. WhichThat is a restrictive pronoun that refers to a direct noun. In the example, "I don’t trust fruits and vegetables that aren’t organic," I’m referring to all non-organic fruits or vegetables. In other words, I only trust fruits and vegetables that are organic. Which introduces a relative clause. It allows qualifiers that may not be essential. In the example, "I recommend you eat only organic fruits and vegetables, which are available in area grocery stores," you don’t have to go to a specific grocery store to obtain organic fruits and vegetables.
-
Their vs. There vs.They'reTheir is the possessive case of the pronoun they, meaning belonging to them and is generally plural. Example: Someone left their book on the table. There is an adverb that means in or at that place. It is what’s known as an adverb of place, which answers the question where an action is taking place. Example: She is there now. They're is a contraction of the words they and are. Example: They’re mastering the differences between three homophones!
-
Whether vs. IfWhether and If are not interchangeable. Whether expresses a condition where there are two or more alternatives. Example: I don’t know whether I’ll go running tonight. If expresses a condition where there are no alternatives. Example: If my knee doesn't hurt, I will go for a run tonight.
-
Who vs. WhomUsing who or whom depends on whether you’re referring to the subject or object of a sentence. Use Who when replacing the pronouns he, she, we, in the subject of a sentence. Example: "Who loves you?" can replace "He loves you." Use Whom when replacing the pronouns, him, her, them, in the object of a sentence. Example: "I consulted an attorney whom I met in New York." can replace "I consulted him."
-
Your vs. You’reYour is a possessive adjective used to show ownership, and is usually followed by a noun (including gerunds). Example: Your hair looks great today! You're is a contraction of the phrase you are. Example: I think you’re the perfect match for the job.
-
Colon MistakesA colon is used after a complete sentence to introduce a word, phrase, clause, list, or quotation.

Correct: People move to Florida for three reasons: the warmer weather, the beach, and the theme parks.
-
Comma SplicingThese happen when a comma separates two clauses that could be two separate sentences. To fix comma splices, you can add a semicolon or a period, use a conjunction like and/or/but or some other connecting word, or rewrite the sentence entirely. Example: Incorrect: He checked out a book on gardening, she went to wait in the car. Correct: He checked out a book on gardening while she went to wait in the car. Correct:He checked out a book on gardening; she went to wait in the car. Correct: She waited in the car while he checked out a book on gardening.
-
Superfluous CommasThrowing commas around liberally when they aren’t necessary. is a common writing mistake. There are dozens of examples of this error, but here are a few common mistakes. Example 1: Incorrect: The woman never went into the city, because she didn’t feel comfortable driving in traffic. Correct: The woman never went into the city because she didn’t feel comfortable driving in traffic. Example 2: Incorrect: He wants to get a degree in engineering, or medicine. Correct: He wants to get a degree in engineering or medicine. Example 3: Incorrect: Sam knew immediately, what was going to happen next. Correct: Sam knew immediately what was going to happen next. Example 4: Incorrect: Old cars, that have been left in a junkyard, are an eyesore. Correct: Old cars that have been left in a junkyard are an eyesore. Example 5: Incorrect: The bouquet of flowers on the table, belongs to Mary. Correct: The bouquet of flowers on the table belongs to Mary.
-
Missing Comma after Introductory ElementA comma should be used after an introductory word, phrase, or clause. Using a comma gives the reader a slight pause after an introductory element and often can help avoid confusion. Example 1: Incorrect: In case you haven’t noticed my real name doesn’t appear in the article. Correct: In case you haven’t noticed, my real name doesn’t appear in the article.
-
No Comma in a Compound SentenceA comma separates two or more independent clauses in a compound sentence separated by a conjunction. The comma goes after the first clause and before the coordinating conjunction that separates the clauses. Example: Incorrect: She was beautiful and she was happy and she was full of life. Correct: She was beautiful, and she was happy, and she was full of life.
-
Overuse of ApostrophesApostrophes indicate one of two things: Possession, as in Sara's iPad, or letters missing, as in it's (for it is, in which the second "i" is missing.) Apostrophes do not belong on plurals. When you have more than one of something, there is no need to add an apostrophe. The same goes for your last name. If you want to refer to your family, but don't want to list everyone's first name write The Johnsons not "The Johnson's." Years also shouldn't have apostrophes. For example, 1980s is correct but "1980's" is not.
-
Lack of Parallel StructureFaulty parallelism occurs when two or more parts of a sentence are similar in meaning but not parallel (or grammatically similar) in form. It often occurs with paired constructions and items in a series. Example 1: Incorrect: He wanted to learn more about careers in programming, engineering, biochemist, and research scientist. Correct: He wanted to learn more about careers in programming, engineering, biochemistry. Example 2: Incorrect: The key directives of his boss were clear: - Meet monthly sales quotas. - Aggressive marketing techniques. - Reporting in every day. Correct: The key directives of his boss were clear: - Meet monthly sales goals. - Practice aggressive marketing techniques. - Report in every day.
-
Misplaced or Dangling ModifierA misplaced modifier is a word, phrase, or clause that is separated improperly from the word it modifies or describes. Sentences with this error can sound awkward, ridiculous, or confusing. A dangling modifier is a word or phrase that modifies a word that is not clearly stated in the sentence. Example 1: Incorrect: While walking on the sidewalk, Mary found a sparkly girl’s bracelet. Correct: While walking on the sidewalk, Mary found a girl’s sparkly bracelet. Example 2: Incorrect: After finally setting off on the trail, the morning felt more exciting. Correct: After finally setting off on the trail, he felt the morning was more exciting.
-
Run-On SentenceA run-on sentence occurs when you connect two main clauses with no punctuation. Example 1: Incorrect: She tried to sneak out of the house her mother saw her leaving. Correct: She tried to sneak out of the house, but her mother saw her leaving. Example 2: Incorrect: He ran through the field as fast as he could all the while rain was soaking him to the bone. Correct: He ran through the field as fast as he could. All the while rain was soaking him to the bone
-
Sentence FragmentsSentence fragments are incomplete sentences that don’t have an independent clause. A fragment may lack a subject, a complete verb, or both. Sometimes fragments depend on the proceeding sentence to give it meaning. Example 1: Incorrect: He gave his mother an extravagant gift after the argument. In spite of everything. Correct: In spite of everything, he gave his mother an extravagant gift after the argument Example 2: Incorrect: The boys snuck home late that night. Then waited for the consequences. Correct: The boys snuck home late that night, then waited for the consequences.
-
Sentence SprawlA sentence can become a burden to read when there are too many equally weighted phrases. Example 1: Incorrect: Jason was planning to attend his friend’s wedding on June 30, but at the last minute he found out he had jury duty, so he couldn’t attend the wedding, and he felt really guilty about it. Correct: Unexpectedly Jason was called for jury duty and couldn’t attend his friend’s June 30 wedding. He felt guilty about missing it.
-
Split InfinitivesAn infinitive is the word “to” with a verb. A split infinitive separates the word “to” and the verb with another word (often an adverb). There are no grammar rules that prohibit split infinitives, but many experts disapprove of them. If the sentence sounds awkward by correcting the split, our rule of thumb is to go with what makes the most sense in the context of your writing and for the ease of reading. (For example, “To boldly go where no man has gone before” would sound awkward and less powerful as, “To go boldly where no man has gone before.”) Example 1: Incorrect: She tried to quickly finish the book before she had to leave. Correct: She tried to finish the book quickly before she had to leave.
-
Subject-Verb Agreement ErrorsThe subject and verb of a sentence must agree with one another in number, whether they are singular or plural. If the subject of the sentence is singular then its verb must also be singular. Example 1: Incorrect: An important part of my life have been the people who stood by me. Correct: An important part of my life has been the people who stood by me. Example 2: Incorrect: The two best things about the party was the food and the music. Correct: The two best things about the party were the food and the music.
-
Vague Pronoun ReferenceA pronoun can replace a noun, and its antecedent should be the person, place, or thing to which the pronoun refers. A vague pronoun reference (including words such as it, that, this, and which) can leave the reader confused about what or to whom the pronoun refers. Example 1: Incorrect: Don felt a lot of anger and bitterness as a result of Marie’s decision. This is what ended everything. (What ended everything? Don’s anger and bitterness or Marie’s decision?) Correct: Don felt a lot of anger and bitterness as a result of Marie’s decision. Her choice ended everything.
