One-Point English Lesson – Prepositions of Time

Introduction

Mastering the usage of prepositions of time is essential for developing a strong command of the English language. NJCLT, a trusted name in language training, is here to provide you with a comprehensive English grammar lesson on the prepositions "at," "in," and "on." In this lesson, you will learn about the correct usage and nuances of each preposition in different time-related contexts. Let's dive in!

Using "at" for Specific Points in Time

When it comes to referring to specific points in time, the preposition "at" is used. It helps express precise moments or hours. For example:

• I have an important meeting at 9:00 AM.
• The movie starts at 7:30 PM.
• I usually have lunch at noon.

By using "at," you can indicate a particular time that something happens or is supposed to happen. It is important to remember that when using "at," the emphasis is on a specific time point.

Using "in" for Lengthier Periods of Time

Unlike the precise moments represented by "at," the preposition "in" is used to refer to longer periods of time. Let's explore a few examples:

• I will go on vacation in July.
• They completed the project in three weeks.
• The conference will take place in the morning.

When "in" is used, it indicates an approximate time frame or duration rather than a specific point in time. It highlights a general period within which an event occurs or will occur.

Using "on" for Days and Dates

The preposition "on" is primarily used to specify days, dates, and specific occasions. Take a look at the following examples:

• The party is happening on Monday.
• I have an appointment on June 20th.
• We celebrate Christmas on December 25th.

If you want to highlight a particular day or date, using "on" is the right choice. It is important to note that "on" is used when referring to specific calendar days or dates.

Additional Considerations

While the primary usage of these prepositions has been discussed, it's also important to be aware of some additional considerations:

1. Exceptions:

There are certain expressions where different prepositions are used instead of "at," "in," or "on." For instance, we say "at night" and "in the afternoon" instead of using "in" or "on." These exceptions become familiar with practice and exposure to the language.

2. Idiomatic Expressions:

English is full of idiomatic expressions that use specific prepositions of time. For example, "in the long run" means a situation or result in the distant future, and "at the crack of dawn" means very early in the morning.

Conclusion

Mastering the prepositions "at," "in," and "on" is vital for accurate and effective communication in English. By understanding the subtle differences in usage, you will be able to express time-related concepts with precision and clarity.
