Diction refers to an author’s word choice. The APA manual stresses the importance of proper word choice because academic writing should be as precise as possible. Follow the word choice guidelines below to make sure you are communicating in a clear, precise manner.
Accept and except: "Accept" means to agree; "except" suggests exclusion. Example: I accepted all the applicants except Mr. Lee.
Advice and advise: "Advice" is a noun and is a suggestion; "advise" is a verb and is the act of giving that suggestion. Example: I advise all of my clients to get more sleep; most of them take this advice.
Affect and effect: "Affect" is a verb that refers to the influence that something has on something else; "effect" is a noun that refers to a result. Example: Did Vitamin C affect the patients? I am curious if it had any effect.
Allude and elude: "Allude" is in indirect reference to something else; "elude" means to avoid. Example: The criminal was able to elude the police when his friend alluded that the shopkeeper was responsible for the crime.
Although and while: "Although" is a conjunction that indicates a contrast (despite something being the case). "While" is a conjunction that indicates a time and is also a noun referring to a period of time. Example: Although he disliked rain, he went out while it was raining to find his missing cat. Note that in APA style, use of "while" is more restrictive than in common usage.
Among and between: "Between" is reserved for two items; "among" is used for three or more. Example: It was easy to choose between the peach cobbler and the apple crisp; however, it was difficult to decide among the brownie, ice cream, and custard.
Any body, anybody, any one, and anyone: "Any body" and "any one" are adjectives modifying a noun. Example: I like to swim in any body of water. I could not single out any one person. "Anybody" and "anyone" are pronouns. Example: He would go to prom with anyone. Anybody would do!
Assume and presume: To "assume" something is to base information on nothing. Example: I assume that next year’s party will be fun. To "presume" something is to base information on evidence or facts. Example: I presume the shirt is on sale because it was on the sale rack.
Assure, ensure, and insure: "Assure" means to confirm (usually with an individual or group of individuals); "ensure" means to make sure that something is accomplished; and "insure" means to protect from harm (usually referring to protection from financial loss). Example: I assured the home owners that their homes were insured. I ensured this protection by providing them with a sound policy.
Attribute and contribute: An "attribute" is a noun that refers to a characteristic of something. Example: His best attribute was his sense of humor. To "attribute," as a transitive verb, is to explain something by noting its cause. Example: I attribute my winning personality to my humor. To contribute is to give something to help people or causes. Example: She likes to contribute time to her local soup kitchen.
Because: See Since and because.

Casual and causal: "Casual" refers to something that is informal or unplanned. Example: They wore casual clothes for the party. "Causal" refers to the cause of something or to something that makes things happen. Example: The causal factor in the students’ declining energy was the absence of lunch.
Causal: See Casual and causal.
Cite, sight, and site: "Cite" means to refer to another source for a claim you make. Example: Make sure to cite the author of each source you discuss. "Sight" means the visual sense (what you can see). Example: Using sight as well as smell, the dog navigated the maze. "Site" means a location, as in a study site. Example: The researcher found the middle school to be a useful site for studying bullying behaviors.
Complement and compliment: "Complement" suggests that one item helps complete another one; "compliment" is an act of praise. Example: I complimented Dustin on how his eyes complemented his complexion.
Conscience and conscious: "Conscience" refers to one’s morality; "conscious" is in reference to one’s awareness of his or her surroundings. Example: The hypnotist had no conscience when his subjects were unconscious.

Drug and dragged: See Dragged and drug.
Effect: See Affect and effect.
Elude: See Allude and elude.

Fewer and less: "Fewer" should be used with things that can be counted; "less" should be used for amounts you cannot count. Example: Fewer boys than girls were upset; however, the girls were less upset than anticipated.
Former and latter: These terms should be used sparingly and only when referring to two items. "Former" means the first item referred to (remember both "former" and "first" begin with "f"), and "latter" means the last item (both "latter" and "last" begin with "l"). Example: Writing specialists like reading and writing; students prefer the former. (This means students prefer reading.)
If and whether: "If" and "whether" are often interchangeable. However, it is important to use "if" when referring to something that is conditional. Example: Bring your key if you come to the house. (This sentence is conditional because you only need to bring the key if you come to the house.) Example: Bring your key whether or not you come to the house. (This sentence is not conditional because you will have to bring your key either way.)
Implicit: See Explicit and implicit.
Imply and infer: See Infer and imply.
Infer and imply: "Infer" means to deduce something and is what readers do. "Imply" means to hint or suggest, and it is what writers do. Example: She described a red, octagonal sign in the parking lot. I inferred it was a stop sign. Example: The teacher implied that there might be pop quiz tomorrow.
Insure: See Assure, ensure, and insure.
Its and it’s: "Its" is the possessive form of "it"; "it’s" is a contraction meaning "it is." Example: The baby saw the dog and grabbed its tail. It’s interesting that she would do that. Note that in APA style, you should avoid contractions, so you would never use "it’s" for a paper in APA style.
Latter and former: See Former and latter.
Lay and lie: "Lay" means to put down an object. Example: She lays the baby in the crib. "Lie" means to put yourself down or to recline. Example: I lie in bed, dreaming of summer.

Peak, peek, and pique: "Peak" means the top or maximum of something. Example: I climbed to the peak of the mountain. "Peek" means to sneak a look at something. Example: The girl peeked at her birthday present when her parents were out. "Pique" means a sudden anger or annoyance at being offended (noun) or to make someone angry (verb).

Example: The principal insisted that the principal component of the school’s success was its teachers. The principal insisted that the teachers taught Darwinian principles.
Proceed: See Precede and proceed.
Sight: See Cite, sight, and site.
Since and because: "Since" is used to indicate time. For example, the dog hasn’t been walked since you started school. "Because" should be used in all other instances, such as causal relationships and to show causation. For example, I want to go to school because I don’t like walking the dog.
Site: See Cite, sight, and site.
Subsequently: See Consequently and subsequently.
Than and then: "Than" suggests a comparison; "then" explains what follows. Example: Ben was faster than Mark. We then knew who the second fastest member of the team was.
That and which: "That" is a restrictive pronoun, meaning what follows is necessary for the reader to understand. "Which" is unrestrictive, suggesting that the following information is an aside. Example: Sticks of dynamite, which we planted last night, will destroy the vault. The vault that was next door, however, was indestructible.
That and who: Use "that" for objects and "who" for people. I know she likes marshmallows that are burnt. (Here the word "that" refers to the marshmallows.) I know someone who likes burnt marshmallows. (Here the word "who" refers to someone.)
Their, there, and they’re: "Their" is a pronoun. "There" is a noun referring to a place. "They’re" is a contraction meaning "they are." Example: They’re going over there. It is their anniversary. Note that in APA style, you should not use contractions.
