What are Prepositions of Time?

Prepositions of time connect nouns to other parts of the sentence, answering the question “when.” The most common prepositions of time are at, ago, before, by, during, for, from, in, on, since, till/until, and to.

Let’s look at some examples:

  • The annual alumni meeting lasted until lunch.
  • We’ll be there by 4:30 p.m.
  • In the summer, these hills look majestic.
  • They told me that they would be done before dinner.
  • He’s been living in Chiang Mai since last year.

Prepositions of Time Rules

Prepositions require objectsPrepositions are parts of prepositional phrases, which include objects. While there are certain sentence structures that break up prepositional phrases, their objects are always identifiable. With prepositions of time, their objects are usually time expressions. Let’s look at some examples:

– Harry stopped at 4 p.m. to focus on another task.
– We will launch on January 16th.
– Jerry has been in the business for 11 years.
PlacementFrom previous examples, we can see that prepositions usually go before their objects. Here are some more examples:

– There are some eggplants in the greenhouse.
– Someone’s at the door.
– I expect the report to be on my desk first thing tomorrow.

There are exceptions with some sentence structure such as questions or reported speech
Standard expressionsAt, in, and on are the three most common prepositions of time. They cause great confusion as the definitions of prepositions can seem arbitrary. Things such as “a long period of time” can mean differently to each person, for example. Fortunately, at, in, and on have become part of standard expressions when indicating dates, days, hours, and so on. There is still a lot to memorize when it comes to these rules, but in time and with consistent practice, you’ll be able to use them correctly and naturally.

At is used for the following:

– hours (at 9 p.m.)
– some parts of the day (at night)
– holidays without the word “day” (at Easter)
– the word “time” (at that time)

In is used for the following:

– some part of the day (in the morning)
– centuries (in the 15th century)
– decades (in the 80s)
– years (in 1994)
– months (in February)
– seasons (in autumn)
– periods of time (in the past)_ the word “weeks” (in two weeks)

On is used for the following:

– days (on Saturday)
– days + parts of the day (on Monday afternoon)
– dates (on September 19)
– specific days (on my birthday)
– holidays with the word “day”

Advice for ESL Students & English Language Learners

Use Grammar ListsEnglish grammar tools such as lists and tables can’t take the place of books, but they can be useful as guides. They simplify grammar concepts into models, patterns, and rules, including valuable sample sentences. They are particularly useful for prepositions because of the scope of the subject. A great way to maximize the benefits of this method is to make your own lists, which you can adjust to fit your learning preferences and language needs.
Use Audio-Visual ResourcesSelf-directed instruction is a crucial supplement to traditional English classes. However, you should use the correct tools to study effectively. By integrating your favorite English language films, TV shows, social media channels, music, and podcasts to your learning routine, you’ll get valuable information on how native and non-native English speakers use English in different real-life situations: social, academic, and professional. Using English-language media purposefully will improve your understanding of expression and communication. This will ultimately advance your vocabulary and sentence construction skills.
Practical UseIt’s an unfortunate truth that many English language learners live or study in places where English isn’t normally used or spoken. This makes studying English twice as challenging as the only real way to develop fluency is to speak regularly. If you are in the same situation, remember that you have the ability to make an “English environment” for yourself. Organizing a study group with like-minded people is a good place to start. It will provide a learning space to explore English with others. Moreover, you can establish personal relationships with English speakers from other countries of backgrounds, which can be instrumental in discussion and role-play exercises.

Common Errors Made by English Learners

Common ErrorsExplanation/Example
Using at, in, and of expressions that don’t need them.There are some time expressions that don’t need the prepositions at, in, and of, but many English learners use them anyway. Take note of the following list and remember that we don’t use at, in, and of for these words and phrases:

– today, tomorrow, yesterday
– last night, last week, last year, etc.
– this morning, this month, this week, etc.
– next week, next month, next year, etc.
– every day, every night, every year, etc.
“I have been studying architecture for three years between 2015 to 2018.”Because of verb tenses, most students automatically use the present perfect continuous every time they use the word “for” over a period of time. This isn’t always the case. In the sentence, it’s clear that the person no longer studies architecture, which they did from 2015 to 2018. Below is the correct sentence:

– I studied architecture for three years between 2015 to 2018.
Since and fromIncorrect: “I’ve been waiting from 9 a.m.”

Correct: I’ve been waiting since 9 a.m.” Remember that since means from a point in time in the past until now. This is the reason we can only use since with perfect tenses, just like the sentence in our examples using “I’ve been.”

Learning Strategies and Best Practices with Prepositions of Time

Prepositions are some of the most commonly used words in English. Because of their quantity and distinctions in meaning, it’s quite a huge challenge to be proficient at using them. Prepositions are rarely studied individually in traditional classroom settings. It’s tedious and time-consuming. Most of the time, English learners learn prepositions through exposure and experience. They hear phrases spoken a certain way and integrate them into their own vocabulary. The following are some best practices to observe when studying and using prepositions of place:

  1. Instead of studying large concepts as a whole, try learning English in portions of the language. In most cases, you don’t need to know the technical rules of English grammar, and prepositions are one of the most complex and confusing things you will ever study. Listen to native speakers and take note of how they use prepositions. Then try using them in your own speech or writing you have an opportunity. Remember that there are standard expressions in English that have always been said that way without getting into the reasons. Why do we say “I’m on the bus” when the bus is an enclosed space? Instead of asking why you should ask “How do I say this correctly?”
  2. There are a lot of prepositions, perhaps not the number of words but definitely the number of meanings. In addition, each one can be used with any noun, making endless configurations possible. If you find yourself uncertain about the right prepositions to use, use a dictionary or a grammar list.
  3. You don’t need to use prepositions. If you’re having difficulty picking the correct preposition, you can practice your paraphrasing skills and reconstruct your sentence in a way that prepositions are not involved or necessary.
  4. Read, practice, talk. The more vocabulary you have acquired, the more accurate you’ll become in choosing not only the right prepositions but also the proper ways of using them.

Additionally, it is important for learners to properly understand preposition form of direction and preposition form of manner.

Prepositions of Time Frequently Asked Questions

Prepositions of time state when something has happened, and connect time expressions to the rest of the sentence. We use the prepositions at, in, and on for this function, as well as several others.

Here are some examples:

– Your interview with Mr. Jorge is at 10 a.m.
– I trained with them from 2018 to 2019.
– There will be a massive sale on Friday.
– She thinks she saw you during the rally.
– You have been reading since you woke up.

Yes, you can. You may have come across notices like this one: “In case of emergency, pull the alarm.” When prepositional phrases start sentences, they don’t always need to be followed by a comma. For example “Down the hole the rabbit went.” You will come across similar sentence structures in books or articles as many writers use this as their style.

Any “most common” vocabulary list in English is never absolute. English is constantly evolving, with new words or phrases gaining popularity all the time and later integrated into standard use. Can you remember the time when google became a verb?

Having said that, this list of the 10 most widely used prepositions may change over time. Most books agree that these are in, on, to, for, at, by, from, with, of, and about. One of the main reasons is that each of those prepositions has multiple meanings with each one having a unique functionality.

It’s a primary rule that they can’t. Prepositional phrases consist of prepositions and their objects, which are either nouns or pronouns. The object of a preposition may be a noun clause in some instances, which contains a verb, but the entire clause still technically functions as a noun and is treated like one.

Gerunds or the present participle forms of verbs are used as nouns and can be part of a prepositional phrase, but they’re longer considered verbs when used in this role.

The types of prepositions are time, place, movement, measure, manner, source, possession, and agency.
