Common Mistakes in English Grammar

Correct Usage of Apostrophes with Numbers

One common mistake that is frequently made in English grammar is the incorrect usage of apostrophes when expressing a period of time involving a number. Specifically, the mistake is often made when referring to a specific number of weeks.

Instead of using "week's time" to indicate a period of time, the correct usage is "weeks' time".

For example:

• Incorrect: I will complete the project in 2 week's time.
• Correct: I will complete the project in 2 weeks' time.

The incorrect usage of the apostrophe in this case implies possession, suggesting that the weeks themselves own or possess the time. However, the intended meaning is to indicate a period of time consisting of multiple weeks.

Using the correct placement of the apostrophe, as seen in the second example, clarifies that the time frame spans across two weeks. This ensures proper understanding and avoids confusion in written communication.

It's important to proofread your written work carefully to catch any mistakes in grammar, including the correct usage of apostrophes. For assistance with grammar checking and proofreading, you can try the Linguix grammar checker.
