Prepositions are small but mighty words that help us understand relationships between different elements within a sentence. Among these, prepositions of time are particularly crucial as they help convey when an action occurs. Mastering the use of prepositions of time can significantly enhance your fluency and comprehension in English. In this article, we’ll delve into the most common prepositions of time: “in,” “on,” and “at,” along with some less common but equally important ones such as “by,” “until,” “since,” and “for.” By the end of this guide, you’ll have a comprehensive understanding of how to use these prepositions correctly.
Understanding “In”
The preposition “in” is used to denote larger periods of time. It’s often employed when referring to months, years, centuries, seasons, and parts of the day. Here are some examples:
– **Months**: “My birthday is in July.”
– **Years**: “The company was founded in 1995.”
– **Centuries**: “Many technological advancements occurred in the 20th century.”
– **Seasons**: “We love going to the beach in summer.”
– **Parts of the day**: “I usually meditate in the morning.”
Additionally, “in” can be used to indicate a future period:
– “The meeting will start in 10 minutes.”
Common Mistakes with “In”
Many learners often confuse “in” with “on” or “at.” For instance, saying “in Monday” instead of “on Monday” is incorrect. Remember, “in” is used for more extended periods, not specific days or times.
Mastering “On”
The preposition “on” is used for more specific times than “in.” It is primarily employed when referring to days, dates, and specific parts of days. Here are some examples:
– **Days**: “I have a meeting on Monday.”
– **Dates**: “Christmas is on December 25th.”
– **Specific parts of the day**: “I have a dentist appointment on Monday morning.”
Common Mistakes with “On”
A frequent error among learners is using “on” for months or years, such as “on July” or “on 1995.” These should be “in July” and “in 1995,” respectively. Another common mistake is using “on” instead of “at” for precise times, like saying “on 5 PM” instead of “at 5 PM.”
Perfecting “At”
“At” is the preposition used for the most specific times. It is commonly used to talk about clock times, specific moments, and periods such as festivals or the weekend. Here are some examples:
– **Clock times**: “The train departs at 6 PM.”
– **Specific moments**: “The fireworks will start at midnight.”
– **Festivals or weekends**: “We usually go to our grandparents’ house at Christmas.”
Common Mistakes with “At”
A typical mistake is using “at” for days or parts of the day. For example, saying “at Monday” or “at the morning” is incorrect. These should be “on Monday” and “in the morning,” respectively.
Lesser-Known Prepositions of Time
While “in,” “on,” and “at” are the most common prepositions of time, there are several others that are equally important for conveying time accurately.
By
The preposition “by” is used to indicate a deadline or the latest time by which something will happen. For example:
– “I need to finish this report by Friday.”
– “She promised to be back by 6 PM.”
Until
“Until” (or “till”) is used to indicate that something will continue up to a specific point in time. For example:
– “We will wait until you arrive.”
– “The store is open until 9 PM.”
Since
“Since” is used to denote the starting point of an action that continues up to the present. For example:
– “I have been working here since 2010.”
– “She has lived in Paris since last summer.”
For
“For” is used to specify the duration of an action. For example:
– “I have been studying English for two years.”
– “They have been traveling for three months.”
Practical Tips for Mastering Prepositions of Time
Understanding and using prepositions of time correctly can be challenging, but with some practical tips, you can master them effectively.
