Is When a Preposition? The Truth About This Commonly Misused Word in English Grammar

Is When a Preposition?

Historical Usage of ‘When’

In the past, ‘when’ was often considered a preposition. It was used to indicate a point in time, similar to other prepositions like ‘at’ and ‘on’. For example, “I will see you when the sun sets.” In this sentence, ‘when’ is used to indicate a point in time when the speaker will see the other person.

Modern Usage of ‘When’

However, in modern English, ‘when’ is not generally considered a preposition. Instead, it is more commonly used as a conjunction or an adverb. As a conjunction, it is used to connect two clauses or phrases together, such as “I will go to the store when I finish work.” As an adverb, it is used to modify a verb and indicate the time at which an action occurs, such as “When I woke up, it was already noon.”

It is worth noting that some grammarians still consider ‘when’ to be a preposition in certain contexts, such as when it is used to indicate a point in time, as in “I will see you when the sun sets.” However, this usage is becoming less common in modern English.

In conclusion, while ‘when’ may have been considered a preposition in the past, it is now more commonly used as a conjunction or an adverb in modern English.

Role of ‘When’ in Sentences

‘When’ is a word that can be used as a conjunction, an adverb, or a relative adverb. In this section, we will focus on its role as a conjunction and adverb in sentences.

‘When’ as a Conjunction

As a conjunction, ‘when’ is used to connect two clauses that show a cause-and-effect relationship. It is often used to express a specific time or moment in the past, present, or future. Here are some examples:

• When I arrived at the party, everyone had already left.
• I’ll call you when I get home.
• When she finishes her homework, she can watch TV.

In these examples, ‘when’ is used to introduce a subordinate clause that explains the reason or condition for the main clause.

‘When’ as an Adverb

As an adverb, ‘when’ is used to modify a verb or an entire sentence to indicate the time or moment of an action. It can be used to refer to the past, present, or future. Here are some examples:

• I remember when we first met.
• When you’re ready, we can start the game.
• When it rains, it pours.

In these examples, ‘when’ is used to indicate the time or moment of an action or event. It can also be used to express a general truth or fact.

Overall, ‘when’ is a versatile word that can be used as a conjunction or an adverb to express time and cause-and-effect relationships in sentences. By understanding its different roles, learners of English can improve their grammar and communication skills.

Common Mistakes and Misconceptions

‘When’ vs ‘While’

One common mistake that English learners make is confusing the use of ‘when’ and ‘while’. While ‘when’ is a subordinating conjunction, ‘while’ is a coordinating conjunction. This means that ‘when’ introduces a dependent clause, while ‘while’ introduces an independent clause. For example, “I was cooking dinner when the phone rang” is correct, while “I was cooking dinner while the phone rang” is incorrect.

Incorrect Placement of ‘When’

Another common mistake is placing ‘when’ in the wrong part of a sentence. ‘When’ should be used to introduce a dependent clause that describes a specific time or event, but it should be placed in the correct position within the sentence. For example, “I will call you when I arrive at the airport” is correct, while “When I arrive at the airport, I will call you” is incorrect.

It is important to note that ‘when’ is not a preposition. It is a subordinating conjunction that is used to introduce a dependent clause. However, many English learners mistakenly believe that ‘when’ is a preposition because it is often used to indicate time. It is important to understand the correct use of ‘when’ in order to avoid common mistakes and misconceptions.

Practical Exercises and Examples

Identifying ‘When’ in Sentences

When is a word that can be used as a conjunction, adverb, or pronoun. It is not a preposition. However, there are some cases where ‘when’ can be used as a preposition. To identify ‘when’ as a preposition, look for the following:

• When followed by a noun or noun phrase
• When indicating a time period
• When indicating a duration of time
• When indicating a point in time

For example:

• “I will meet you when the sun goes down.” (preposition)
• “When I was a child, I loved playing outside.” (conjunction)
• “He knew when to leave the party.” (adverb)
• “When is your birthday?” (pronoun)

Using ‘When’ Correctly in Writing

When using ‘when’ as a preposition, it is important to use it correctly in writing. Here are some examples:

• “I will be there when the movie starts.” (correct)
• “I will be there at when the movie starts.” (incorrect)
• “I will be there when the movie starts at 7 PM.” (correct)
• “I will be there when the movie starts at 7 PM sharp.” (correct)

It is also important to use ‘when’ appropriately in relation to other prepositions. For example:

• “I will meet you when you get off the train.” (correct)
• “I will meet you off the train when you get.” (incorrect)

In the first sentence, ‘when’ is used as a preposition indicating a point in time. In the second sentence, ‘off’ is used as a preposition indicating a location. Using ‘when’ in this way can cause confusion and should be avoided.
