Learning prepositions can be one of the most challenging aspects of mastering the English language. Prepositions of time are particularly essential because they help us communicate when events occur. If you can correctly use prepositions of time, you will be able to express yourself more clearly and understand others better. In this article, we will delve into the various prepositions of time, their correct usage, and common mistakes to avoid.
Understanding Prepositions of Time
Prepositions of time are words that link nouns, pronouns, or phrases to a point in time. The most common prepositions of time in English are at, on, and in. Each of these prepositions has specific rules governing its usage.
Using “At”
The preposition at is used to indicate a specific point in time. Here are some examples:
– **At** precise times: “I wake up at 7 a.m.”
– **At** holidays and festivals: “We exchange gifts at Christmas.”
– **At** specific periods of the day: “She always drinks coffee at noon.”
It’s important to note that at is not used with dates or longer periods. You wouldn’t say, “I have a meeting at Monday.” Instead, you would use on.
Using “On”
The preposition on is used for days and dates. Here are some examples:
– **On** specific days: “He works on Mondays.”
– **On** specific dates: “Her birthday is on July 20th.”
– **On** specific days of events: “We met on New Year’s Eve.”
Remember, on is not used for general periods or specific points in time. For example, you wouldn’t say, “I will see you on noon.”
Using “In”
The preposition in is used for longer periods such as months, years, centuries, and longer spans of time. Examples include:
– **In** months: “We are going on vacation in August.”
– **In** years: “He was born in 1990.”
– **In** centuries: “This castle was built in the 16th century.”
– **In** periods of the day: “I feel tired in the afternoon.”
However, in is not used for specific times or days. You wouldn’t say, “I have an appointment in Monday.”
Other Common Prepositions of Time
While at, on, and in are the most commonly used prepositions of time, there are other prepositions that you should be aware of. These include before, after, during, until, and by.
Using “Before” and “After”
These prepositions indicate relative time.
– **Before**: “I need to finish this report before noon.”
– **After**: “We’ll go to the park after lunch.”
Using “During”
The preposition during is used to indicate a period within which something happens.
– **During**: “He fell asleep during the movie.”
Using “Until” and “By”
These prepositions are used to indicate a deadline or a specific time limit.
– **Until**: “She will stay here until Friday.”
– **By**: “You need to submit the assignment by Monday.”
Common Mistakes and How to Avoid Them
Even advanced learners can make mistakes with prepositions of time. Here are some common errors and tips to avoid them.
Confusing “At” with “On” or “In”
One common mistake is using at when on or in should be used. For example:
Incorrect: “I will meet you at Monday.”
Correct: “I will meet you on Monday.”
To avoid this, remember that at is used for specific times, on is used for days and dates, and in is used for longer periods.
Using “In” for Specific Times
Another frequent error is using in for specific times.
Incorrect: “The train arrives in 5 p.m.”
Correct: “The train arrives at 5 p.m.”
To prevent this mistake, remember that in is used for longer periods like months, years, and centuries, not for specific times.
Misusing “During” and “For”
Learners often confuse during with for.
Incorrect: “I stayed there during two weeks.”
Correct: “I stayed there for two weeks.”
To avoid this, note that during is used to indicate when something happens, while for indicates the duration of time something lasts.
