This article will delve into prepositions that indicate time, a crucial aspect of effective communication. Understanding and correctly using these prepositions will significantly enhance your fluency and comprehension.
Understanding Prepositions of Time
Prepositions of time are used to express when something happens. These words are indispensable for giving context to actions and events. Some of the most commonly used prepositions of time include: at, on, in, by, before, after, during, for, since, and until. Each of these prepositions has specific rules and contexts in which they are used. Let’s explore each one in detail.
At
The preposition at is used to indicate a specific point in time. It is typically used with:
– Clock times: “The meeting starts at 3 PM.”
– Specific moments: “I will call you at lunchtime.”
– Festivals: “We always visit our grandparents at Christmas.”
At is not used with longer periods such as days, months, or years. It focuses on pinpointing an exact moment.
On
The preposition on is used for days and dates. It is the go-to preposition for specifying particular days or parts of days. For example:
– Days of the week: “She has a dance class on Monday.”
– Specific dates: “My birthday is on July 15th.”
– Special days: “We met on New Year’s Day.”
Using ‘On’ for Specific Days
On is also employed when referring to specific days in expressions like:
– “I will see you on my wedding day.”
– “She was born on a rainy day.”
In
The preposition in is used for more extended periods, such as months, years, decades, centuries, and longer periods of time. For example:
– Months: “We are going on vacation in August.”
– Years: “She graduated in 2005.”
– Decades: “Jazz music became popular in the 1920s.”
– Centuries: “That castle was built in the 15th century.”
In can also be used to indicate a future point relative to the present moment:
– “I will be ready in five minutes.”
– “The project will be completed in two weeks.”
By
The preposition by is used to indicate a deadline or the latest time by which something will happen. It implies that the action can happen any time before the deadline, but no later. For example:
– “Please submit your report by Friday.”
– “She promised to return by noon.”
By with Passive Voice
By is also frequently used in passive constructions to indicate the agent performing the action:
– “The book was written by George Orwell.”
Before and After
The prepositions before and after are used to indicate a point in time relative to another event. They are essential for sequencing events and expressing temporal relationships.
– Before: “We should finish the work before dinner.”
– After: “She will call you after the meeting.”
During
The preposition during is used to indicate an event happening within a particular period or simultaneously with another event. It is commonly used with nouns indicating periods of time or events. For example:
– “He fell asleep during the movie.”
– “We met several times during the conference.”
For
The preposition for indicates the duration of an action or event. It answers the question “how long?” and is used with periods of time:
– “They have been traveling for two weeks.”
– “I will stay here for a few days.”
Since
The preposition since is used to indicate the starting point of an action or event that continues up to the present. It answers the question “from when?” and is commonly used with the present perfect tense:
– “She has been working here since 2010.”
– “I have not seen him since last week.”
Until
The preposition until (or till) indicates the end point of a period of time. It is used to express when an action or event stops:
– “We will wait until you arrive.”
– “The store is open until 9 PM.”
