Definition of “Until”
“Until” is a versatile word primarily used as a preposition and a conjunction. It specifies a point in time up to which an action continues or a state remains valid. As a preposition, “until” is followed by a noun or pronoun. As a conjunction, it introduces a clause. Its core function is to establish a temporal boundary, indicating the cessation or termination of an event or condition.
In simpler terms, “until” tells us how long something will last. It marks the endpoint of a duration, providing clarity and precision in communication.
For instance, “I will wait until 5 PM” means the waiting action will stop at 5 PM. The word derives from Old English and has maintained its core meaning related to time and duration throughout its linguistic history.
Structural Breakdown
The structural role of “until” varies depending on whether it functions as a preposition or a conjunction. Understanding these structures is key to using “until” correctly.
- As a Preposition: “Until” + Noun/Pronoun (e.g., until tomorrow, until the end). The noun or pronoun specifies the time at which the action or state ceases.
- As a Conjunction: “Until” + Clause (Subject + Verb + Object/Complement) (e.g., until the rain stops, until he arrives). The clause provides more detailed information about the terminating event.
The clause following “until” often uses the present simple tense to refer to future events, especially after verbs of waiting, staying, and similar actions. This is a common pattern in English grammar for subordinate clauses indicating time.
Types and Categories of “Until” Usage
The word “until” can be categorized based on its specific function within a sentence. These categories help to clarify its meaning and application.
Expressing Time Duration
This is the most common usage, indicating how long an action or state continues before stopping. Example: “I will stay here until the meeting ends.”
Indicating Condition Termination
Here, “until” specifies the condition that must be met for an action to stop or a state to change. Example: “You can’t leave until you finish your work.”
Negative Contexts
“Until” is often used in negative sentences to emphasize the continuation of a state or action up to a specific point. Example: “I didn’t know about it until yesterday.”
“Until” as a Conjunction
When used as a conjunction, “until” connects two clauses, indicating that the action in the main clause continues up to the time specified in the subordinate clause. Example: “She practiced the piano until her fingers were sore.”

Usage Rules for “Until”
Using “until” correctly involves understanding several key rules, including tense agreement and avoiding double negatives. These rules ensure clarity and grammatical accuracy in your sentences.
Tense Agreement with “Until”
When “until” introduces a clause, pay attention to tense agreement. If the main clause is in the future tense, the subordinate clause often uses the present simple tense to refer to future events. For example: “I will wait until he arrives.” (Future in main clause, present simple in subordinate clause).
However, if the main clause is in the past tense, the subordinate clause should also be in the past tense. For example: “I waited until he arrived.” (Past in both clauses).
Avoiding Double Negatives
Avoid using double negatives with “until.” A double negative can create confusion and change the intended meaning of the sentence. Instead of saying “I won’t leave until you don’t apologize,” say “I won’t leave until you apologize.”
Formal vs. Informal Usage
In formal writing, it’s generally preferred to use “until” rather than its shortened form “’til” or “till.” While “’til” and “till” are acceptable in informal contexts, “until” maintains a more professional tone. Also, avoid starting a sentence with “until” in formal writing; rephrase the sentence for better flow and clarity.
Common Mistakes with “Until”
Several common mistakes can occur when using “until.” Recognizing these errors can help you avoid them and improve your grammatical accuracy.
| Incorrect | Correct | Explanation |
|---|---|---|
| I will wait until he will arrive. | I will wait until he arrives. | Incorrect tense usage in the subordinate clause. |
| I won’t leave until you don’t apologize. | I won’t leave until you apologize. | Double negative; the “don’t” is unnecessary. |
| Until the rain stops, we can’t go out. | We can’t go out until the rain stops. | While grammatically correct, starting with “until” is less common in formal contexts. |
| I waited until he will arrive. | I waited until he arrived. | Incorrect tense usage. Past tense should be consistent. |
| She will not start until he won’t come. | She will not start until he comes. | Double negative to be avoided. |
| Until I don’t finish, I can’t rest. | Until I finish, I can rest. | Double negative makes the sentence confusing. |
| He didn’t call until he hadn’t received the message. | He didn’t call until he received the message. | Avoid using double negative constructions. |
| I’m not leaving until they won’t pay me. | I’m not leaving until they pay me. | Double negatives should always be avoided. |
| She didn’t speak until nobody asked. | She didn’t speak until somebody asked. | The original sentence doesn’t make sense. |
| They hadn’t eaten until they didn’t cook. | They hadn’t eaten until they cooked. | Avoid double negatives for clearer meaning. |

Frequently Asked Questions (FAQ)
This section addresses some frequently asked questions about the use of “until.”
- What is the difference between “until” and “till”?
“Until” and “till” are generally interchangeable and have the same meaning. “Till” is simply a shorter, less formal version of “until.” “‘Til” is also used, but it’s considered even more informal and should be used sparingly in formal writing. The word ” ’til ” is considered incorrect by some because it implies that the word “until” is shortened from “untill”, which is not true.
- Can I start a sentence with “until”?
While grammatically correct, starting a sentence with “until” is generally discouraged in formal writing. It can sometimes make the sentence sound awkward or less polished. It is preferable to rephrase the sentence so that “until” appears in the middle or later part of the sentence.
- How do I avoid double negatives with “until”?
To avoid double negatives, ensure that the clause following “until” is not negated. For example, instead of saying “I won’t leave until you don’t apologize,” say “I won’t leave until you apologize.” The single negative in the main clause is sufficient to convey the intended meaning.
- What tense should I use after “until”?
The tense used after “until” depends on the tense of the main clause. If the main clause is in the future tense, use the present simple tense in the subordinate clause (e.g., “I will wait until he arrives”). If the main clause is in the past tense, use the past tense in the subordinate clause (e.g., “I waited until he arrived”).
- Is it correct to say “until when”?
The phrase “until when” is generally considered redundant because “until” already implies a time limit. It’s more common and grammatically sound to simply ask “How long will it last?” or “How long will you wait?”
- Can “until” be used with a gerund?
Yes, “until” can be followed by a gerund (a verb form ending in -ing that functions as a noun), although this usage is less common. For example: “He kept working until collapsing from exhaustion.” In this case, “collapsing” acts as a noun, specifying the point at which his working stopped.
- What is the difference between “by” and “until”?
“By” indicates a deadline or a point in time at or before which something must be completed. “Until” indicates a duration, specifying how long something will continue. For example, “Please submit your application by Friday” means the application must be submitted on or before Friday. “The library is open until 8 PM” means the library will remain open up to 8 PM.
