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.

Is After a Preposition: Understanding Its Usage and Common Misconceptions
is after a preposition is a phrase that often sparks debate among English language learners and even native speakers. The question revolves around whether the verb "is" can or should appear immediately following a preposition, and if so, under what grammatical conditions. This topic is particularly relevant in understanding syntactical structures and ensuring clear, grammatically correct communication. In this article, we will investigate the nuances of "is after a preposition," analyze its grammatical validity, and clarify common misconceptions surrounding this construction.
The Role of Prepositions and the Verb “Is” in English Grammar
Prepositions are words that establish a relationship between other words in a sentence, often indicating direction, place, time, or introducing objects. Examples include "in," "on," "at," "after," and "before." Traditionally, prepositions are followed by noun phrases, pronouns, or gerunds (verbs ending in -ing functioning as nouns). For example, in the sentence "She sat on the chair," the preposition "on" is followed by the noun "chair."
The verb "is" is the third-person singular present tense form of "to be." It functions as a linking verb, connecting the subject of a sentence to a subject complement, often an adjective or noun. Because "is" is a verb, its placement directly after a preposition raises questions from a grammatical standpoint.
Is "Is" After a Preposition Grammatically Correct?
In standard English grammar, a verb in its base form or conjugated form typically does not follow a preposition directly. Instead, prepositions are followed by objects—usually nouns, pronouns, or gerunds. For example:
- Correct: She is interested in learning.
- Incorrect: She is interested in learn.
Here, "learning" (the gerund) functions as a noun, allowing the preposition "in" to be followed by a noun phrase.
Given this rule, the verb "is" immediately following a preposition would generally be considered ungrammatical because "is" is neither a noun nor a gerund. Consider the sentence:
- Incorrect: This is something I am proud of is.
- Correct: This is something I am proud of.
In this context, placing "is" after "of" does not conform to grammatical norms.
However, one might encounter constructions where "is" appears after a preposition, but these are typically part of a larger clause or phrase rather than a direct preposition-verb sequence.
When Does “Is” Appear After a Preposition?
Despite the general rule, "is" can appear after a preposition when it introduces a dependent clause, often beginning with a relative pronoun or conjunction. This is not the preposition directly followed by "is," but rather the preposition followed by a clause containing "is." For example:
- "I am aware of what is happening."
- "He is different from how it is normally done."
In these sentences, the preposition ("of," "from") is followed by a clause ("what is happening," "how it is normally done"), where "is" functions as part of the verb phrase within the subordinate clause. This is grammatically sound because the preposition’s object is the entire clause, not just the verb "is."
Examples Illustrating “Is” After a Prepositional Phrase
To elaborate, consider the following sentences:
- "The reason for why he is late is unclear."
- "She is not responsible for what is broken."
- "There is a difference between what is expected and what is delivered."
In these examples, the preposition ("for," "between") introduces a clause in which "is" serves as the verb. The phrase following the preposition is a noun clause acting as the object of the preposition. This is a crucial distinction because it validates the presence of "is" after a preposition within a specific grammatical context.
Common Misconceptions About “Is After a Preposition”
A widespread misunderstanding is that any instance of "is" following a preposition is incorrect. This stems from confusion between single-word objects of prepositions and clause objects. Many learners mistakenly assume that "is" can never appear after a preposition, ignoring the fact that the preposition may govern an entire clause.
Another misconception relates to the infamous "preposition stranding" debate, which concerns whether it is acceptable to end a sentence with a preposition. While this is tangentially related, it sometimes leads to overly rigid interpretations of prepositional use, affecting judgments about "is after a preposition."
Why This Matters in Writing and Communication
Clarity and grammatical accuracy are paramount in professional and academic writing. Misusing or misunderstanding the placement of "is" after a preposition can lead to awkward phrasing or grammatical errors, which may undermine the writer’s credibility. Understanding when "is" can correctly appear after a preposition equips writers and speakers to construct complex sentences without sacrificing grammatical integrity.
Moreover, in the context of search engine optimization (SEO), precise language and grammatical correctness enhance the readability and authority of online content. Correct usage of phrases involving prepositions and verbs like "is" improves user engagement and search rankings by providing clear and authoritative information.
Comparing Gerunds and Clauses After Prepositions
It is important to distinguish between gerunds and clauses as objects of prepositions when analyzing the presence of "is" after a preposition.
- Gerunds: These are verbs ending in -ing that function as nouns. After prepositions, gerunds are the standard verb form. For example, "She is interested in learning."
- Clauses: When a preposition introduces a clause, the clause acts as the object. The verb "is" can appear within this clause. For example, "He is proud of what is achieved."
This distinction clarifies why "is" does not directly follow a preposition as a single verb but can be part of a clause that follows a preposition.
Examples of Gerund vs. Clause after Prepositions
| Preposition + Gerund | Preposition + Clause with "is" |
|---|---|
| She is good at singing. | She is good at what is sung. |
| They talked about going to the park. | They talked about when it is best to go. |
| He left without saying goodbye. | He left without knowing what is next. |
This comparison highlights how "is" appears naturally in clauses following prepositions, while gerunds directly follow prepositions when representing actions.
Implications for Language Learners and Educators
For language learners, particularly those studying English as a second language, the concept of "is after a preposition" can be confusing. Teachers and educational materials should emphasize the grammatical structures that permit "is" within clauses following prepositions rather than treating the phrase as a standalone grammatical anomaly.
Furthermore, understanding these nuances aids in mastering complex sentence construction, improving both comprehension and expressive abilities. It also reduces the risk of overgeneralizing grammar rules, such as incorrectly prohibiting any verb after a preposition without considering clause usage.
Strategies to Master the Concept
- Practice identifying clauses: Learners should focus on recognizing noun clauses introduced by relative pronouns after prepositions.
- Distinguish between gerunds and clauses: Understanding the difference helps clarify when "is" can appear after a preposition.
- Use authentic reading materials: Exposure to professional writing demonstrates natural usage.
- Engage in targeted exercises: Sentence analysis and transformation tasks can solidify understanding.
By adopting these strategies, learners can confidently navigate the complexities of prepositional phrases involving the verb "is."
Conclusion: Clarifying the Use of “Is After a Preposition”
While at first glance the phrase "is after a preposition" might suggest an ungrammatical construction, a deeper grammatical analysis reveals that the verb "is" can indeed appear after a preposition when embedded within a clause that functions as the object of that preposition. Recognizing the difference between a verb following a preposition directly and a verb within a clause after a preposition is essential for accurate grammar usage.
This understanding not only enriches grammatical knowledge but also enhances clarity in communication, making it an important consideration for writers, educators, and language learners alike.
