Conjugating verbs can seem daunting, especially if you’re new to grammar or learning a new language. The verb “to use” is a common and essential verb in the English language. Understanding how to conjugate it properly will significantly improve your communication skills, both written and spoken. This guide provides a thorough breakdown of how “to use” changes across different tenses, aspects, moods, and voices.
Understanding Verb Conjugation Basics
Before diving into the specifics of “to use,” let’s recap some fundamental concepts of verb conjugation. Verb conjugation is the process of changing the form of a verb to reflect different grammatical categories like person (first, second, third), number (singular, plural), tense (present, past, future), aspect (simple, continuous/progressive, perfect, perfect continuous), mood (indicative, imperative, subjunctive), and voice (active, passive).
Knowing these categories is essential because they dictate which form of “to use” is grammatically correct in a particular sentence. Ignoring conjugation rules can lead to confusion and miscommunication.
English verbs, unlike those in many other languages, have relatively simple conjugation patterns. However, understanding those patterns and identifying irregular verbs is critical. “To use” is a regular verb, making its conjugation straightforward.
Conjugating “To Use” in Simple Tenses
The simple tenses (present, past, and future) are the foundation of verb conjugation. They express actions that occur habitually, occurred in the past, or will occur in the future, respectively.
Simple Present Tense
The simple present tense describes actions that happen regularly or are generally true. Here’s how “to use” is conjugated in the simple present:
- I use
- You use
- He/She/It uses
- We use
- You use
- They use
Notice that the third-person singular (he, she, it) takes an “-s” ending. This is a fundamental rule for simple present tense conjugation in English. Remember this “-s” ending for the third person singular; it’s a common mistake. For example, “He uses the computer every day,” not “He use the computer every day.”
Simple Past Tense
The simple past tense describes actions that happened and finished at a specific time in the past. Since “to use” is a regular verb, we form the simple past by adding “-ed” to the base form of the verb.
- I used
- You used
- He/She/It used
- We used
- You used
- They used
The simple past tense of “to use” is the same for all subjects. This makes it very easy to learn and apply. Note that the pronunciation of “used” can vary depending on its function in the sentence.
Simple Future Tense
The simple future tense describes actions that will happen in the future. We form the simple future tense using the auxiliary verb “will” followed by the base form of the verb.
- I will use
- You will use
- He/She/It will use
- We will use
- You will use
- They will use
Another way to express the simple future is by using “going to.”
- I am going to use
- You are going to use
- He/She/It is going to use
- We are going to use
- You are going to use
- They are going to use
Both “will” and “going to” are commonly used to express the future, but they can carry slightly different nuances. “Will” often implies a decision made at the moment of speaking, while “going to” suggests a pre-existing plan or intention.
Conjugating “To Use” in Continuous (Progressive) Tenses
The continuous or progressive tenses describe actions that are ongoing or in progress at a particular time. They emphasize the duration of the action. These tenses require a form of the auxiliary verb “to be” and the present participle (verb + “-ing”).
Present Continuous Tense
The present continuous tense describes actions that are happening now or around the present time.
- I am using
- You are using
- He/She/It is using
- We are using
- You are using
- They are using
For example, “I am using the computer right now” indicates that the action of using the computer is currently in progress. The present continuous can also be used to describe future plans, particularly when they are already arranged.
Past Continuous Tense
The past continuous tense describes actions that were in progress at a specific time in the past.
- I was using
- You were using
- He/She/It was using
- We were using
- You were using
- They were using
For instance, “I was using the phone when you called” implies that the action of using the phone was ongoing at the moment the phone call occurred.
Future Continuous Tense
The future continuous tense describes actions that will be in progress at a specific time in the future.
- I will be using
- You will be using
- He/She/It will be using
- We will be using
- You will be using
- They will be using
For example, “I will be using the lab tomorrow afternoon” suggests that the action of using the lab will be ongoing during that specific time.
Conjugating “To Use” in Perfect Tenses
The perfect tenses describe actions that have been completed at a certain point in time. They focus on the result or consequence of an action rather than its duration. These tenses require a form of the auxiliary verb “to have” and the past participle (in this case, “used”).
Present Perfect Tense
The present perfect tense describes actions that started in the past and continue to the present, or actions that have a result or relevance in the present.
- I have used
- You have used
- He/She/It has used
- We have used
- You have used
- They have used
For example, “I have used this software before” implies that the speaker has experience using the software, and that experience is relevant to the present situation.
Past Perfect Tense
The past perfect tense describes actions that were completed before a specific time in the past.
- I had used
- You had used
- He/She/It had used
- We had used
- You had used
- They had used
For example, “I had used the computer before he arrived” indicates that the action of using the computer was completed before another action (his arrival) occurred in the past.
Future Perfect Tense
The future perfect tense describes actions that will be completed before a specific time in the future.
- I will have used
- You will have used
- He/She/It will have used
- We will have used
- You will have used
- They will have used
For instance, “I will have used all the data by tomorrow” suggests that the action of using the data will be completed before the specified time (tomorrow).
Conjugating “To Use” in Perfect Continuous Tenses
The perfect continuous tenses combine the features of both perfect and continuous tenses. They describe actions that started in the past, have been ongoing, and continue until a specific point in time. These tenses require a form of “to have,” “been,” and the present participle (verb + “-ing”).
Present Perfect Continuous Tense
The present perfect continuous tense describes actions that started in the past and have continued up to the present. It emphasizes the duration of the action.
- I have been using
- You have been using
- He/She/It has been using
- We have been using
- You have been using
- They have been using
For example, “I have been using this computer for five hours” implies that the speaker started using the computer five hours ago and is still using it now.
Past Perfect Continuous Tense
The past perfect continuous tense describes actions that had been in progress before a specific time in the past.
- I had been using
- You had been using
- He/She/It had been using
- We had been using
- You had been using
- They had been using
For instance, “I had been using the phone for an hour when it suddenly died” indicates that the action of using the phone was ongoing for an hour before another event (the phone dying) occurred in the past.
Future Perfect Continuous Tense
The future perfect continuous tense describes actions that will have been in progress before a specific time in the future.
- I will have been using
- You will have been using
- He/She/It will have been using
- We will have been using
- You will have been using
- They will have been using
For example, “I will have been using the software for three hours by the time you arrive” suggests that the action of using the software will have been ongoing for three hours before a specific event (your arrival) in the future.
Conjugating “To Use” in Different Moods
Beyond tense and aspect, verb conjugation also involves different moods, which indicate the speaker’s attitude towards the action. The three main moods in English are indicative, imperative, and subjunctive.
Indicative Mood
The indicative mood is the most common mood, used to express facts or opinions. All the examples above in the tenses and aspects were in the indicative mood. It simply states something.
For instance, “I use the computer” (simple present) is a statement of fact.
Imperative Mood
The imperative mood is used to give commands or make requests. The subject is usually implied (you).
- Use the instructions carefully.
- Don’t use that tool without permission.
The imperative mood is simple; it typically uses the base form of the verb. The imperative mood is powerful for giving direct instructions or making clear requests.
Subjunctive Mood
The subjunctive mood expresses wishes, suggestions, hypothetical situations, or conditions that are contrary to fact. While less common in modern English, it’s still important to recognize.
In the present subjunctive, the verb takes the base form, regardless of the subject.
- It is essential that he use the correct tool. (Not “uses”)
- I suggest that she use a different approach.
In the past subjunctive, the verb “to be” takes the form “were” for all subjects.
- If I were to use that method, I would fail.
The subjunctive mood often appears in formal writing and speech, particularly after verbs like “suggest,” “recommend,” “insist,” and “demand.” It adds a layer of nuance and formality to communication.
Conjugating “To Use” in Active and Passive Voice
Voice refers to whether the subject of the sentence performs the action (active voice) or receives the action (passive voice).
Active Voice
In the active voice, the subject performs the action.
- I use the tool.
- He used the machine.
- They will use the data.
The active voice is generally preferred because it’s more direct and concise.
Passive Voice
In the passive voice, the subject receives the action. The passive voice is formed using a form of the auxiliary verb “to be” and the past participle (used).
- The tool is used by me.
- The machine was used by him.
- The data will be used by them.
The passive voice can be useful when the actor is unknown, unimportant, or when you want to emphasize the action rather than the actor. For example, “The data was used to generate the report.”
“Used To” vs. “To Use”
It’s crucial to distinguish between the verb “to use” and the phrase “used to.” “Used to” expresses a past habit or state that is no longer true.
- I used to use this software all the time. (I no longer use it)
The structure of “used to” is different from the simple past tense of “to use.” Be careful not to confuse these two distinct grammatical structures. The negative and interrogative forms of “used to” often involve “did”:
- I didn’t use to like coffee.
- Did you use to live here?

Can “to use” be used in the passive voice, and if so, how does it work?
Yes, the verb “to use” can indeed be used in the passive voice. The passive voice is used when the subject of the sentence receives the action, rather than performing it. The focus shifts to the object being acted upon.
Examples include: “The tool is used by the carpenter” (present simple passive), “The equipment was used yesterday” (past simple passive), and “The resources will be used efficiently” (future simple passive). The passive voice is formed using a form of “to be” and the past participle “used.”
