prep

The word "prep" has evolved from its origins as an abbreviation of "preparation." While it still fundamentally means to get something ready, its usage has broadened over time. At its core, to prep something is to take the necessary steps to make it suitable for a specific purpose.

You might prep your skin before applying makeup, meaning you cleanse and moisturize it. A mechanic would prep a car for inspection by checking all the fluids and systems. Students prep for tests by studying and reviewing material. The noun form, "prep," often refers to this preparatory work itself: "The kitchen prep took hours."

In school use, especially in British English, "prep" can also mean homework or study work done outside normal class time. A student might say, "I have a lot of prep tonight," meaning there is a lot of homework to finish.

However, "prep" also has a specific meaning in education. A "prep school" (short for preparatory school) is a private school designed to prepare students for the next level of education, such as college or university. These schools often emphasize character development and leadership skills alongside academics. In a related sense, "prep" (or "preppy") can describe a classic style of dress or a subculture associated with these institutions—think polo shirts, blazers, and a neat, traditional look.

Finally, you might hear "prep" used informally as shorthand for the act of getting yourself ready—"I need to prep myself mentally for this presentation." Whether it's a task, an ingredient, a school, or your own mindset, "prep" is all about taking action to ensure everything is in place and ready to go.
