Understanding Prepositions
What Are Prepositions?
Prepositions are words that establish relationships between nouns, pronouns, and other parts of a sentence. They often describe time, place, direction, or manner. For example:
- Time: “She arrived at 5 PM.”
- Place: “The keys are on the table.”
- Direction: “He walked into the room.”
Common Prepositions
Here are some frequently used prepositions:
- In, on, at, by, for, of, with, about
| Preposition | Usage | Examples |
| In | Indicates inclusion within something | – She is in the room.- I live in New York.- He is in love. |
| On | Indicates a position atop a surface or a subject of focus | – The book is on the table.- Focus on your goals.- We’re working on the project. |
| At | Refers to a specific point or location | – She is at the door.- We met at the park.- He’s good at math. |
| By | Indicates proximity, method, or agent | – The house is by the river.- The letter was sent by post.- It was written by her. |
| For | Indicates purpose, recipient, or benefit | – This gift is for you.- I’m working for a better future.- This is important for the team. |
| Of | Indicates possession, relation, or origin | – The cover of the book is torn.- He is a friend of mine.- She is proud of her work. |
| With | Indicates accompaniment or instrumentality | – I went with my friends.- The package comes with instructions.- Cut it with scissors. |
| About | Refers to a subject or topic | – This book is about history.- Let’s talk about the meeting.- She’s curious about his plans. |
The Correct Usage of “Interested In”
Definition and Context
The phrase “interested in” indicates curiosity, involvement, or enthusiasm about something. It shows that a person has a focus on or is engaged with a particular subject.
Examples in Sentences
- “I am interested in learning new languages.”
- “He’s interested in art and design.”
- “Are you interested in joining our book club?”
Dialog vs. Dialogue Which One Should You Use?
Why “Interested In” is Correct
The phrase “interested in” is correct because it shows engagement, curiosity, or focus on a particular subject or activity. The preposition “in” implies involvement, which aligns with the meaning of the word “interested.”
Scenario:
Sarah loves gardening and spends her weekends researching plants. When someone asks about her hobbies, she says, “I am interested in gardening.” The preposition “in” emphasizes her active engagement with gardening, making the sentence meaningful and grammatically correct.
Examples:
- “He’s interested in learning about different cultures.”
- “They are interested in volunteering at the community center.”
- “I’m interested in exploring career opportunities in technology.”
Why “Interested On” is Incorrect
The phrase “interested on” is incorrect because the preposition “on” is typically used to describe a physical surface, focus, or dependency—not engagement or curiosity. Using “on” with “interested” creates a mismatch in meaning.
Scenario:
Imagine John is reading about space exploration. If he says, “I am interested on space,” it sounds unnatural and grammatically wrong. The preposition “on” does not convey involvement but rather suggests physical placement or dependency, which doesn’t fit here.
Examples of Incorrect Usage:
- “She is interested on the new movie release.”
- “I’m interested on how this device works.”
- “They are interested on traveling next summer.”
Corrected Versions:
- “She is interested in the new movie release.”
- “I’m interested in how this device works.”
- “They are interested in traveling next summer.”
By using “in”, the sentences convey curiosity or involvement, making them grammatically correct and natural.
Comparison Table: “Interested In” vs. “Interested On”
| Aspect | Interested In | Interested On |
| Meaning | Indicates engagement, curiosity, or involvement with a subject or activity. | Incorrect usage; does not convey involvement or curiosity appropriately. |
| Preposition Usage | The preposition “in” emphasizes being inside or part of something. | The preposition “on” typically refers to a surface, focus, or dependency, which is not suitable here. |
| Examples | – “I’m interested in science.”- “She’s interested in art.”- “They are interested in volunteering.” | – “I’m interested on science.” (Incorrect)- “She’s interested on art.” (Incorrect)- “They are interested on volunteering.” (Incorrect) |
| Correctness | Grammatically correct and widely accepted in English. | Grammatically incorrect and unnatural. |
| Common Contexts | Used when talking about hobbies, areas of study, or topics of curiosity. | Rarely (if ever) used correctly with the word “interested.” |
| Grammatical Rule | The verb “interested” naturally pairs with the preposition “in” to convey involvement. | Using “on” with “interested” breaks the natural pairing and leads to confusion. |
| Why It’s Used | “In” aligns with the meaning of “interested,” showing a connection or engagement. | “On” implies a focus or dependency, which does not fit with the meaning of “interested.” |
Key Takeaway: Always use “interested in” to express curiosity or involvement, and avoid “interested on,” as it is grammatically incorrect.
Common Misconceptions
Examples of Incorrect Usage
- “I am interested on this topic.”
- “He’s interested on working with you.”
- “They’re interested on traveling next month.”
Explanation of Incorrect Usage
These sentences feel awkward because “on” does not logically connect with the concept of being involved or engaged. “On” is better suited for physical placement or topics like focus and dependency (e.g., “on the table,” “on the matter”).
When to Use “On” with Other Verbs
Appropriate Contexts for “On”
The preposition “on” is suitable for:
- Discussing physical locations: “The book is on the desk.”
- Indicating dependence: “He relies on her advice.”
- Talking about focus: “We’re working on a solution.”
Examples with Different Verbs
