Common mistake per vs pre

One common mistake that many people make is confusing the use of "per" and "pre." These two words may sound similar, but they have different meanings and should not be used interchangeably.


The word "per" is often used as a preposition, meaning "for each" or "according to." It is commonly used in situations where a rate or ratio is being described.

  • She earns $10 per hour at her job.
  • The recipe calls for two cups of flour per batch.
  • The car drives an average of 30 miles per gallon.


On the other hand, the word "pre" is a prefix that is used to indicate "before" or "prior to." It is often used to form words such as "preparation," "preview," or "predecessor."

  • I need to do some pre-work before starting the project.
  • We watched a preview of the upcoming movie.
  • John is the predecessor of Sarah in this position.

Using these words incorrectly can lead to confusion and miscommunication. It is important to understand the proper usage of "per" and "pre" to ensure clear and effective communication.
