What is the rule for using 'is' after a preposition?

The verb 'is' does not directly come after a preposition; instead, a noun, pronoun, or gerund typically follows a preposition. For example, in 'after the meeting,' 'meeting' is a noun following the preposition 'after.'

Can 'is' appear immediately after a preposition in a sentence?

No, 'is' is a verb and does not directly follow a preposition. Prepositions are followed by objects (nouns, pronouns, or gerunds), not verbs like 'is.'

What usually follows a preposition like 'after'?

A preposition like 'after' is usually followed by a noun, pronoun, or gerund. For example, 'after the show,' 'after him,' or 'after running.'

Is it correct to say 'after is' in English grammar?

Generally, 'after is' is not correct because 'is' is a verb and prepositions are followed by objects, not verbs. However, 'after is' might appear in indirect questions or complex sentences but not as a direct preposition-verb combination.

Can a clause starting with 'is' come after a preposition?

Typically, no. Prepositions are followed by noun phrases, not clauses starting with verbs like 'is.' To use a clause after a preposition, a subordinating conjunction or proper structure is needed.

How can you correctly use a verb related to 'is' after a preposition?

You can use a gerund (verb + -ing) after a preposition. For example, instead of 'after is,' use 'after being' as in 'after being late.'

Why is 'after is' considered incorrect in standard English?

Because prepositions require an object (noun, pronoun, or gerund), and 'is' is a linking verb, not an object. Therefore, 'after is' violates grammatical rules.

What is an example of a correct phrase using 'after' followed by a verb form?

A correct phrase is 'after finishing the work,' where 'finishing' is a gerund following the preposition 'after.'

Can pronouns follow a preposition instead of 'is'?

Yes, pronouns can correctly follow a preposition. For example, 'after him' is correct, whereas 'after is' is not.

IS AFTER A PREPOSITION

Is After a Preposition: Understanding Its Role and Usage in English Grammar is after a preposition is a phrase that might initially sound unusual or confusing, especially when you’re diving into the depths of English grammar. But it touches on a fundamental aspect of how sentences are structured and how meaning is conveyed. Prepositions are tiny words that pack a big punch—they link nouns, pronouns, and phrases to other words, showing relationships of time, place, direction, cause, and more. So, understanding what happens when “is” comes after a preposition can help clarify sentence construction, avoid common mistakes, and improve your overall fluency. In this article, we’ll explore what it means when “is” follows a preposition, why it might happen, and how it fits into English syntax. Along the way, we’ll cover related grammatical concepts, give practical examples, and share tips for using prepositions correctly with verbs like “is.”

What Does “Is After a Preposition” Mean?

At its core, “is after a preposition” refers to the grammatical positioning of the verb “is” following a prepositional phrase or a preposition itself. Typically, prepositions are followed by noun phrases or pronouns that act as objects of the preposition. For example, in the sentence:

“She sat **on** the chair.”

Here, “on” is the preposition, and “the chair” is its object. Notice that “is” does not usually follow a preposition directly because verbs don’t function as objects of prepositions. However, the phrase “is after a preposition” may come up when discussing certain sentence structures where it seems that “is” appears after a preposition, or when explaining why this is unusual or incorrect. It’s an opportunity to understand how prepositions govern the words that come next and how “is” as a linking verb fits into sentence patterns.

Why Verbs Like “Is” Don’t Usually Follow Prepositions

Prepositions require objects to complete their meaning. These objects are typically nouns, pronouns, or noun phrases—not verbs. Since “is” is a verb (the third-person singular present form of “to be”), it cannot serve as an object of a preposition. For instance, the following sentence is incorrect:

Incorrect: *“She is fond of is.”*

This sentence sounds awkward because “is” cannot be the object of the preposition “of.” Instead, the object should be a noun or pronoun:

Correct: “She is fond of him.”

This grammatical rule is why, in standard English, you won’t find “is” directly after a preposition acting as its object.

The Role of Prepositions and Their Objects

To better grasp why “is” doesn’t follow a preposition, it’s helpful to review how prepositions function within sentences.

Prepositions Link and Show Relationships

Prepositions are words like “in,” “on,” “at,” “by,” “for,” “with,” “about,” and many others. Their primary job is to connect a noun or pronoun to another part of the sentence, showing relationships such as:

Location: “The book is **on** the table.”
Time: “She arrived **after** lunch.”
Direction: “He walked **towards** the park.”
Cause or purpose: “They left **because of** the storm.”

The key here is that the preposition must be followed by its object, which answers questions like “where?” “when?” or “why?”

Objects of Prepositions: Nouns and Pronouns

Since prepositions require objects, these are usually nouns, pronouns, or noun phrases. Examples include:

Nouns: “The gift is **for** Sarah.”
Pronouns: “I’m waiting **for** her.”
Noun phrases: “They walked **through** the dark forest.”

Verbs, including “is,” don’t fit into this role. That’s because verbs express actions or states of being and can’t serve as objects that prepositions govern.

When “Is” Appears After a Prepositional Phrase

Sometimes, you might see sentences where “is” follows a prepositional phrase rather than a single preposition. This can give the impression that “is” comes after a preposition, but technically, it’s after the entire phrase. Consider this example:

“The key **to the house** is missing.”

Here, “to” is the preposition, “the house” is its object forming the prepositional phrase “to the house,” and then “is” follows as the main verb of the sentence. The verb “is” is not the object of the preposition; it belongs to the main clause. This structure is quite common and perfectly grammatical. It shows that while verbs don’t come directly after prepositions, they can appear immediately after prepositional phrases depending on sentence construction.

Examples of Verbs Following Prepositional Phrases

“The book **on the shelf** is new.”
“The students **in the class** are attentive.”
“The man **with the hat** is my uncle.”

In each sentence, the prepositional phrase acts as an adjective describing the subject, and the verb “is” follows to link the subject with the predicate.

Common Mistakes Involving “Is” and Prepositions

Understanding that “is” cannot be the object of a preposition helps avoid common grammatical errors. Here are some pitfalls to watch out for:

Using “Is” as an Object of a Preposition

Incorrect: “He depends on is.”
Correct: “He depends on her.”

The verb “is” cannot replace a noun or pronoun as the object of “on.”

Confusing Prepositions with Conjunctions

Sometimes, people mistakenly follow prepositions with clauses starting with “is,” which causes confusion.

Incorrect: “They talked about is being late.”
Correct: “They talked about his being late.”

In formal English, when a verb follows a preposition, it’s often turned into a gerund (verb + -ing) or preceded by a possessive pronoun.

Tips for Using Prepositions and the Verb “Is” Correctly

To avoid confusion and grammatical errors, keep these practical tips in mind:

Remember that prepositions require objects: These objects should be nouns, pronouns, or noun phrases—not verbs like “is.”
Use gerunds after prepositions when a verb is needed: For example, “She is interested in learning,” not “She is interested in learn.”
Recognize that “is” often follows prepositional phrases, not prepositions alone: As in “The key to the door is missing,” where “is” links the subject and predicate.
When in doubt, rephrase sentences: Sometimes changing the structure can make the sentence clearer and more grammatical.

Understanding Related Concepts: Linking Verbs and Prepositional Phrases

The verb “is” is a linking verb, which means it connects the subject of a sentence to a subject complement, such as an adjective or noun that describes the subject. Prepositional phrases often function as modifiers, providing additional information about the subject or object. By recognizing how linking verbs and prepositional phrases interact, you can better understand the placement of “is” in sentences:

“The house **on the hill** is old.” (Linking verb “is” connects “the house” with “old,” while “on the hill” modifies “house.”)

This interaction exemplifies why “is” doesn’t directly follow a preposition but can come right after a prepositional phrase.

Using “Is” in Passive Voice After Prepositional Phrases

Another interesting instance is when “is” appears in passive voice constructions with prepositional phrases:

“The report **by the manager** is approved.”
“The decision **of the committee** is final.”

Here, the prepositional phrases “by the manager” and “of the committee” specify agents or sources, and “is” serves as the passive auxiliary verb. This highlights the versatility of “is” in different syntactic contexts involving prepositions.

Final Thoughts on “Is After a Preposition”

The phrase “is after a preposition” brings attention to an important grammatical principle: prepositions govern objects that are nouns or pronouns, not verbs like “is.” While “is” itself does not directly follow prepositions as their object, it frequently appears after entire prepositional phrases as the main verb linking subjects and complements. Understanding this distinction helps clarify sentence structure, avoid common errors, and master the use of prepositions and linking verbs in English. By focusing on how prepositions function and where verbs like “is” fit within sentence patterns, learners gain confidence and precision in their language use.
