Common Grammar Mistake: "Through out" instead of "Throughout"

One common grammar mistake that many people make is using the phrase "through out" instead of the correct term "throughout." Though the two may sound similar, they have different meanings and usage rules.

Understanding the Difference

The phrase "throughout" is an adverb which means "in every part of" or "during the whole time or extent of." It is used to describe actions or events that occur in all locations or throughout a specific period.

On the other hand, "through out" is an incorrect spelling and is considered a common error in written English. It is a combination of the preposition "through" and the adverb "out," which creates confusion and changes the intended meaning.


  • Incorrect: She wore her coat through out the day.
  • Correct: She wore her coat throughout the day.
  • Incorrect: The cat wandered through out the house.
  • Correct: The cat wandered throughout the house.
