“Fewer” is used with countable objects (those that can be counted one by one, like toes and cookies). “Less” is used for singular mass nouns that can’t be counted separately (like grass or milk). Here’s a fun trick to help you remember: Fewer = count (same number of letters when you count them), and less = mass (same number of letters, and their “word butts”—ending in “ss”—are the same).

Katrina’s loves classical movies (e.g., Casablanca, Some Like It Hot, and On the Waterfront).

Though they sound like they mean the same thing, and are sometimes mistakenly used interchangeably, “imply” and “infer” have opposite meanings, like “push” and “pull.” To “imply” (an outward action) means to indirectly suggest something. To “infer” (in inward action) means to deduce or conclude.

The trick is to remember that “lay” requires a direct object, but “lie” does not. Aside from a falsehood, “lie” means to recline or be in a prone position. “Lay,” on the other hand, means to place something somewhere.

Toby and I went to the movies.
Santa left presents for me and my sister, but not for our dog Chase.
Note: “I” comes second in the grouping; “me” comes first.
Pro tip: When in doubt on which to use, remove the other person from the sentence. So, for the first example, try: I went to the movies. It wouldn’t be “Me went to the movies,” so “I” is the correct choice. For the second example, try: Santa left presents for me. It wouldn’t be “Santa left presents for I,” so “me” is the correct choice.

Like many entries in this list, these homophones sound the same but have completely different meanings. “Principal” has a number of meanings, depending on whether it’s used as a noun, adjective, or verb, but its general connotation means chief, main, or primary. When used as a noun, a “principal” is a person of high authority or prominence, like the head of a school, a principal on a loan, or a principal player in a crime. When used as an adjective, “principal” means leading or primary, such as a primary cause or reason. A “principle,” meanwhile, is a noun meaning a tenet, rule, or standard.

The ball, which has three red spots, sat in the corner of the room.
The ball that has three spots sat in the corner of the room.
Note: In the first example, the nonrestrictive clause provides more detail about the ball, but it’s not essential to the sentence. In the second example, the restrictive clause is used to differentiate that ball from the other balls, so it can’t be removed without changing the meaning.
Also note: In these uses, “which” always follows a comma; “that” does not.
“That” is for objects, while “who” is for people (and pets, if you prefer). The rule: things that, people who.
Many of the doctors who get their medical degrees at Emory move to pursue fellowships in a specific specialty.

Note: Even though they are made up of people, groups, teams, and other collective nouns are considered things. Also note: In “a group of people who tango,” “who” is describing “people” not “group,” so it gets a “who” not “that.”
