Prepositions are essential components of language that help us express relationships between different elements within a sentence. Among them, prepositions of time play a crucial role in indicating when an action takes place. They help to answer questions such as “When?”, “How long?”, and “Until when?”. In this article, we will delve into the various prepositions of time, their usage, and some common pitfalls to avoid.
Understanding Prepositions of Time
Prepositions of time are words that connect an action or event to a specific point or period in time. The most common prepositions of time in English are at, in, and on, but there are many others, such as before, after, during, by, for, since, until, and throughout. Each of these prepositions has specific rules governing its use.
At
The preposition at is used to denote a specific point in time. It is often used with the following:
– Clock times: “The meeting starts at 3 PM.”
– Specific moments: “I will see you at lunchtime.”
– Festivals or holidays: “We open presents at Christmas.”
Note that at is not used with days or dates. For example, “I will call you at Monday” is incorrect. Instead, you should say, “I will call you on Monday.”
In
The preposition in is used for nonspecific times during a day, month, season, or year. Here are some examples:
– Parts of the day: “I exercise in the morning.”
– Months: “She will arrive in January.”
– Years: “They got married in 1990.”
– Seasons: “We travel in summer.”
It is important to note that in is used for longer periods of time, unlike at, which is used for specific points in time.
On
The preposition on is used to specify days and dates:
– Days of the week: “I have a meeting on Tuesday.”
– Specific dates: “Her birthday is on December 5th.”
– Specific days: “We will see each other on Christmas Day.”
Remember that on is not used for parts of the day, months, or years.
Other Prepositions of Time
While at, in, and on are the most commonly used prepositions of time, there are several others that help to provide more context and detail about the timing of an event or action.
Before
Before is used to indicate that an event happens earlier than a particular point in time:
– “He always has breakfast before work.”
– “We should finish the project before the deadline.”
After
After is used to indicate that an event happens later than a particular point in time:
– “I will call you after the meeting.”
– “They moved to a new house after the wedding.”
During
During is used to indicate that an event happens within a specific period of time:
– “She slept during the movie.”
– “We had a lot of fun during the vacation.”
By
By is used to indicate that something happens not later than a specific time:
– “Please submit your assignment by Friday.”
– “She will be here by 6 PM.”
For
For is used to specify the duration of time over which an action occurs:
– “He has lived here for ten years.”
– “We talked for hours.”
Since
Since is used to indicate the starting point of an action that continues up to the present:
– “I have known her since high school.”
– “They have been working on this project since March.”
Until
Until is used to indicate that an action continues up to a specific point in time:
– “We will stay here until the end of the month.”
– “You can borrow my car until I need it back.”
Throughout
Throughout is used to indicate that an action happens continuously within a specific period of time:
– “He was nervous throughout the entire interview.”
– “We traveled throughout the country.”
Common Mistakes and How to Avoid Them
Using prepositions of time correctly can be challenging, especially for non-native speakers. Here are some common mistakes and tips on how to avoid them:
Confusing At, In, and On
One of the most common mistakes is confusing at, in, and on. Remember the basic rules:
– Use at for specific times and festivals.
– Use in for nonspecific times within longer periods.
– Use on for days and dates.
Overusing During
Another common mistake is overusing during. While during is used to indicate that an event happens within a specific period, it should not replace other prepositions that might be more appropriate. For example, instead of saying “I will call you during the evening,” it is better to say “I will call you in the evening.”
Misplacing By and Until
Learners often confuse by and until. Remember:
– Use by to indicate not later than a specific time.
– Use until to indicate up to a specific point in time.
For example, “The store will be open by 9 AM” means that the store will open no later than 9 AM, while “The store will be open until 9 AM” means that the store will remain open up to 9 AM.
Using Since and For Incorrectly
Since and for are often misused, especially when talking about durations. Remember:
– Use since to indicate the starting point of an action that continues to the present.
– Use for to specify the duration of time.
For example, “I have been studying since 8 AM” means you started studying at 8 AM and are still studying. “I have been studying for three hours” means the total duration of your studying is three hours.
