The preposition “by” identifies the agent, as in “The book was written by J.K. Rowling,” while “with” denotes the instrument, as in “She solved the problem with a calculator.” Understanding these prepositions enhances sentence clarity and improves communication.

Understanding Prepositions of Agency and Instrumentality
Prepositions play a crucial role in our sentences. They allow us to express how different elements in a sentence relate to each other. In English, prepositions of agency and instrumentality are two important types that help clarify the relationship between actions and the entities involved. In this article, we will dive deep into these prepositions, their functions, and how to use them effectively.
What are Prepositions?
Before we explore prepositions of agency and instrumentality, let‚’ clarify what a preposition is. A preposition is a word that links nouns, pronouns, or phrases to other words within a sentence. It usually describes relationships in terms of location, time, or direction.
Definition
Preposition: A word governing, and usually preceding, a noun or pronoun and expressing a relation to another word.
For example, in the sentence, “The cat is on the table,” the preposition “on” indicates a spatial relationship between the cat and the table.
Examples
Example: 1. I placed my book under the bed. Example: 2. The meeting is at noon.
Prepositions of Agency
Prepositions of agency indicate who or what is performing an action. The most common preposition of agency is “by.” For instance, in the sentence, “The book was written by J.K. Rowling,” the preposition “by” shows that J.K. Rowling is the agent behind the action of writing.
Using prepositions of agency helps clarify sentences and ensures that the reader understands who is responsible for the action. Here are some instances where prepositions of agency can be effectively used:
- The painting was created by Picasso.
- The song was performed by Taylor Swift.
- The report was compiled by the research team.
In all of the above examples, the preposition “by” clearly indicates the source of the action, making the sentence clearer and more informative.
Definition
Agent: A person or thing that takes an active role or produces a specified effect.
Prepositions of Instrumentality
In contrast to agency, prepositions of instrumentality describe the means through which an action is accomplished. The common preposition associated with instrumentality is “with.” For example, in the sentence, “She solved the problem with a calculator,” the word “with” shows that the calculator is the tool used to accomplish the action of solving.
It‚’ important to utilize prepositions of instrumentality to provide clarity about the means or instruments involved in an action. Here are some examples for better understanding:
- He cut the paper with scissors.
- She painted the wall with a brush.
- We traveled with a car.
In each of these cases, the preposition “with” indicates the tool or means used to execute the action, enhancing the overall clarity of the sentence.
Definition
Instrumentality: The use of a tool or instrument to achieve an action.
Comparing Agency and Instrumentality
To differentiate between agency and instrumentality, it’s essential to remember that agency refers to who performs the action, while instrumentality pertains to the means through which the action is executed. Understanding this distinction can significantly improve your sentence construction.
❓Did You Know?
Did you know that prepositions have roots in ancient languages? The term comes from the Latin word “praepositus,” meaning “placed before.” This highlights their role in understanding sentence structure.
Creating Sentences with Prepositions of Agency and Instrumentality
Now that we understand both types of prepositions, let’s look at how to create sentences that effectively use them. Here are some structured approaches:
- Identify the action: Determine what action is taking place in the sentence.
- Specify the agent: Think about who is performing the action and introduce them using “by.”
- Determine the instrument: Consider what tools, methods, or means are being used. Use “with” to showcase this.
For example, you could construct the following sentence: “The cake was baked by my grandmother with a new recipe.” Here, “by” indicates the agent (my grandmother), and “with” indicates the means (a new recipe).
Examples
Example: “The fence was painted by John with a spray gun.” Example: “The presentation was designed by the design team with special software.”
Practice Exercises
To master the use of prepositions of agency and instrumentality, practice makes perfect. Here are some exercises you can try:
- Identify the agent in these sentences and replace the verb with a passive form using “by.”
1. The scientist discovered a new species.
2. The architect designed the building. - Convert these sentences to showcase instrumentality, using “with.”
1. He shot the film.
2. She wrote the letter.
Completing these exercises will help reinforce your understanding of the concepts and improve your grammatical skills.
Conclusion
Prepositions of agency and instrumentality are essential components of effective communication in English. By understanding and utilizing these prepositions, you can construct clearer sentences that convey both the doer and the means of action effectively. Remember to practice regularly to build your confidence and mastery of these important grammatical elements.
